[18] It was produced in Europe in 1935 and 1936, and was used in the many standard Ford vehicles based on the car platform of the era. This engine has overhead valves and hemispherical combustion chambers; it produced 138 hp (103 kW) in its most powerful version. Cleveland Motorcycle Manufacturing Company, "Ford Flathead V8 – The Flathead Guide of Death", "A critique of the flathead or side valve engine", "Obsession: Mr. Singh's Search for the Holy Grail", "Reignmaker – 1939 Cadillac Series 39-90", "Kapelstraat 198 8540 Deerlijk – Recent information", Images of each style of Harley-Davidson engine, https://en.wikipedia.org/w/index.php?title=Flathead_engine&oldid=1001714392, Wikipedia articles needing clarification from April 2018, Articles with unsourced statements from January 2019, Creative Commons Attribution-ShareAlike License, This page was last edited on 21 January 2021, at 00:03. [18] The 1951 V8-1CM raised this by 2 hp (1 kW), and 6 lb⋅ft (8 N⋅m) torque,[18] The 1952 V8-MA boosted compression to 7.2:1, power to 125 hp (93 kW), and torque to 218 lb⋅ft (296 N⋅m),[18] while only the name changed, dropping the -MA, for the last year of production, 1953. The French military cranks, at least sometimes, had the 5/8 in (16 mm) plugs in the 3 3/4 in (95 mm) stroke cranks. At most, each bank of the V was an integral block, but many V engines had 4- or even 6-cylinder blocks, with cylinders cast in pairs or triples. This final flathead used a more conventional distributor driven at a right angle to the crankshaft and located at the right front of the engine where it was readily accessible. Nevertheless, the flathead is the little engine that could. After that, almost all major car manufacturers presented V8 engines with various displacements or power levels. The engine was intended to be used for big passenger cars and trucks;[2] it was installed in such (with minor, incremental changes)[3] until 1953, making the engine's 21-year production run for the U.S. consumer market longer than the 19-year run of the Ford Model T engine[3] for that market. The Ford Flathead V8 wasn't the first V8, but when it debuted in the 1932 Model 18, it brought this brilliant engine configuration to the American masses. Two notable exceptions were the American Aeronca E-107 opposed twin aero engine of 1930 and the Continental A40 flat four of 1931, which became one of the most popular light aircraft engines of the 1930s. 18/out/2020 - Flathead para sempre!!!. [18] The engine was very popular as a powerplant for midget race cars after World War II. When Ford Motor Company assumed operations of Lincoln in 1922, they were already producing a flathead engine with Fork and Blade connecting rods which remained in production after Ford took over until 1932. It is spur gear driven; the camshaft's spur gear is made of plastic. In this modern day, it’s hard to imagine how advanced this unit was. These engines can be identified by having the water pumps located at the front of the heads. In the early 1950s, many hot-rodders could not afford to purchase and modify even a "cheap" flathead V-8, and a large investment in machine work and aftermarket parts was necessary to bring a Ford flathead V-8 to even the performance levels of most stock OHV V-8s available at the time. 8RT remained the truck engine designation throughout the entire run from 1948 through 1953 in the U.S (1954 in Canada). The flathead is a gorgeous engine. Although a sidevalve engine can safely operate at high speed, its volumetric efficiency swiftly deteriorates, so that high power outputs are not feasible at speed.

"Then, Now, and Forever" in, This page was last edited on 12 January 2021, at 23:15. [18] It became the V8-68 in 1936, with compression, horsepower, and torque unchanged. It was produced through the 1951 model year. It was initially designated the 8BA (see above) in automobiles and the 8RT in trucks. Richard van Basshuysen, Fred Schäfer: Handbuch Verbrennungsmotor. The sidevalve arrangement was especially common in the United States and used for motor vehicle engines, even for engines with high specific power output. The new design also relocated the water outlet from the front of the heads to the top center of the heads. The left side exhaust manifold exhausted to the front in the 1949–53 Ford cars, where a crossover pipe took the exhaust to the forward end of the right side manifold on the car engines and between the 1st and second cylinder on some trucks, in turn exhausting to a single pipe at the rear. This article is a brief summary of all of Nash's major engine introductions, focusing on major engine designs, upgrades and trends with the goal of illustrating the points in Nash history when major leaps in engine technology occurred. There are still millions of unrestored flathead V8 engines out there in the world, sitting the back corners of barns and garages across America. In early blocks, some cylinder walls were extremely thin due to cores shifting during casting. The Ford flathead V8 was licensed to other producers. [7] In the United States, the flathead V8 was replaced by the more modern overhead-valve Ford Y-block engine in 1954. The exhaust valves were on the inside of the V and exhaust flow was initially downward and passed around the cylinders through the water jacket to exit on the outside of the cylinder block. The engines were essentially identical. Learn more. Increased compression ratios could be cheaply obtained by milling material from the head or by obtaining aluminum heads as aftermarket parts. In 1952 Ford France (who called this engine the Aquilon) created a somewhat bored out version displacing 144 cu in (2.4 L). This little known plugin reveals the answer. ... 48 valves, variable vane turbocharging, optimized inter-cooling, variable valve lift and timing, and other traits of modern engine technology, impressive power could be had, A high displacement engine of, say, 500 cubic inches could plausibly exceed 750 very civilized horsepower. Sorensen, Charles E.; with Williamson, Samuel T.

It can be identified by the four 5/8 in (16 mm) diameter clean-out plugs, two in the front of the front rod throws and two in the back of the back two rod throws of the crankshaft. Known as the V8-9CM in 1949, it featured 6.8:1 compression, 110 hp (82 kW), and 200 lb⋅ft (271 N⋅m) torque,[18] which stayed the same for the 1950 V8-0CM. Types are classified by their displacement. The absence of a complicated valvetrain allows a compact engine that is cheap to manufacture, since the cylinder head may be little more than a simple metal casting. [4] The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some flatheads employ the less common "crossflow" "T-head" variant. Upgrading to the MDL adapter allows the use of a V-8 Fox-body Mustang transmission or the even better gear set found in the new T-5z that MDL offers. Ford flathead V8s were notorious for cracking blocks if their barely adequate cooling systems were overtaxed (such as in trucking or racing). This engine is most commonly referred to as the "60 horse" flathead, or the V8-60. Two passes have to be made in order to break the record. The Ford Flathead V8 was the first mass-market V8 and the starting point for uniquely American performance. The gas flow past the rough sand castings could be greatly improved by polishing the passages. [18], Because of interchangeability, the Mercury crank made a popular upgrade in the 239 among hot rodders. The largest displacement version (at 337 cu in [5.5 L]) of the production Ford flathead V8 engine was designed for large truck service. Production was taken over by Simca in 1954 who began installing it in their Simca Vedette in 1955. Ford flatheads are still hot rodded today, with a special land speed record class for flathead engines. Nordian Services, Ltd. Engine parts in England flathead definition: 1. a thin, flat tropical sea fish that can be eaten 2. a thin, flat tropical sea fish that can be…. Making it practical for the latter was an example of the production development needed to bring a V8 engine to the widely affordable segment of the market. These covers were referred to as lake plugs, the pipes as lake pipes. [18] For 1947 and 1948, only the designation changed, to V8-79 and -89. With 2.6 by 3.2 in (66 by 81 mm) bore and stroke and 6.6:1 compression,[2] the engine was rated 60 hp (45 kW) and 94 lb⋅ft (127 N⋅m). During the 1930s to 1950s, the farm market in North America and parts of Europe demanded ever-increasing power output from farm tractors. (Note: this is true for V-type flathead engines but less of an issue for inline engines which typically have the intake and exhaust ports on the same side of the engine block.) The current record holder achieves 700 hp (525 kW) and 300 mph (483 km/h). The Flathead revised for the new Mercury car line. Modern performance FORD FLATHEAD ENGINES are still hot rodded today, with a special land speed record class for flathead engines. The beauty of the early Model A Ford car and truck was and is the ease with which the engines, frames and bodies could be interchanged. Kirby, a talented machinist, started his career at GM's Hydra-Matic, then worked for aftermarket transmission whiz Doug Nash. The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). Those engines were produced from 1932 to 1938 and were commonly known as “21 stud engines”, due to the head design using 21 head studs In 1937 Ford introduced a 136 cubic inch variant, producing 45hp. The 1933–34 V8-40 raised compression to 6.33:1[18] and power to 75 hp (56 kW). Collectively all 221 motors are commonly referred to as "85 horse" motors. These typically involved installation of free-flowing mufflers, which if at a legal noise level still allowed low frequency sounds to pass, giving a characteristic rumbling dual exhaust sound to these systems. 1949-53 Ford Flathead V8 Engine parts in-stock with same-day shipping. The latest iteration of this engine was used from 1948 to 1953 in the U.S and till 1954 in Canada. As a side benefit to a prospective purchaser of a used vehicle, this also enabled the condition of the connecting rod and main bearings to be determined indirectly by observation of the analog oil pressure gauge after the vehicle was warmed up, provided that oil of normal viscosity was in use. [citation needed] 1935's V8-48 saw compression drop to 6.3:1, but power climb to 85 hp (63 kW), and torque was rated at 144 lb⋅ft (195 N⋅m). Download files and build them with your 3D printer, laser cutter, or CNC. Although the V8 configuration was not new when the Ford V8 was introduced in 1932, the latter was a market first in the respect that it made an 8-cylinder affordable and a V engine affordable to the emerging mass market consumer for the first time. In the song "Hot Rod Lincoln", the engine referred to in the original lyrics was a Lincoln V12 not mentioned in the Commander Cody version. Motor City Speed Equipment Mark Kirby’s engines, engine blocks, and parts. The capacity of the block for over-boring (beyond normal boring for wear compensation) was limited by the configuration and the metal available. The cylinder heads bolt pattern was changed to the modern 24-bolt design to improve sealing. Flathead V8; Ford’s first important and highly influential engine was the Flathead V8, which they introduced in 1932. [18] The 1950 V8-0BA boosted torque by 1 lb⋅ft (1 N⋅m), the 1951 -1BA by 6 lb⋅ft (8 N⋅m) more, while in 1952, as the V8-B2, compression climbed to 7.2:1, power to 110 hp (82 kW), and torque to 194 lb⋅ft (263 N⋅m), then to 196 lb⋅ft (266 N⋅m) in the -B3 of 1953, its final year. Thingiverse is a universe of things. [18] The block was cast as a single piece (monobloc) for durability, and a single-barrel carburetor fed the engine. The engine was on Ward's list of the 10 best engines of the 20th century. It had higher 6.8:1 compression, but performance was unchanged. [18] The designation changed again in 1939, to V8-922A, but the specifications remained the same. The intake manifold fed both banks from inside the vee, but the exhaust ports had to pass between the cylinders to reach the outboard exhaust manifolds, since it didn't use a t-head configuration. [17] They sold many converted Ford N-Series tractors and conversion kits using Ford industrial inline-6 engines and Ford flathead V-8 engines.[17]. For these reasons, the flathead Ford became a favorite among hot-rodders, and this in turn led to a rich supply of aftermarket performance parts. It was the first independently designed and built V8 engine produced by Ford for mass production, and it ranks as one of the company's most important developments. An economizing design feature of this engine was the use of three main bearings to support the crankshaft, rather than the customary five bearings used with most V-8s. The D-motor flathead aero-engines have both spark pugs above the valves. Even though Ford had an engineering team assigned to develop the engine, many of the ideas and innovations were Henry Ford's. This style exhaust was also used legally in sanctioned drag racing and illegally in unsanctioned performance demonstrations. H. Kremser (author): Der Aufbau schnellaufender Verbrennungskraftmaschinen, in Hans List (ed): Die Verbrennungskraftmaschine, volume 11, Springer, Wien 1942. The 4 in (100 mm) crankshafts came in the 1949 to 1953 engines. How Ford's Flathead V8 Engine Works, And Why It DisappearedWhy Can't Pushrod Engine Rev High? Modern use of flathead engines is mainly limited to custom built and restored vehicles. As the V8-09A in 1940, compression, power, and torque were unchanged; in 1941, the V8-19A compression and power were static, but torque rose by 6 lb⋅ft (8 N⋅m), while the 1942 V8-29A increased compression to 6.4:1 and power to 100 hp (75 kW), while torque stayed the same. [11], The Ford flathead V8 has a single camshaft located inside the engine block above the crankshaft. 1942 46 47 48 Ford Flathead V8 Engine Motor 239 Crankshaft 59ab Crank Shaft. Cadillac produced V-16 flathead engines for their Series 90 luxury cars from 1938–1940. [18] Postwar, it became the V8-69 (suffixed "A" in Fords, "M" in Mercurys), with compression 6.75:1, 100 hp (75 kW), and 180 lb⋅ft (244 N⋅m). The flathead mounted the camshaft above the crankshaft, like later pushrod-operated overhead-valve engines. The sidevalve arrangement was especially common in the United States and used for motor vehicle engines, even for engines with high specific power output. Ford introduced the 239 cu in (3.9 L) V8-99A engine with 3.1875 by 3.75 in (80.96 by 95.25 mm) bore and stroke and 6.15:1 compression in 1939. This level of monobloc design for V-8 blocks had been accomplished before,[9] but it had never seen mass production. Even 4-cylinder Ford engines are used to make a retro hot-rod "correct". [9], Sidevalve engines can only be used for engines operating on the Otto principle. Like most other engine blocks then and now, it was cast iron; but the foundry practice (e.g., workflows, materials handling) was a revolutionary advancement in the mass production of castings. Back in 1932, Henry Ford introduced the 221 cubic inch Flathead engine producing 65 HP. Among the latter, the best-known were Funk conversions by brothers Joe and Howard Funk. Looking for even more capacity? Today the flat-head Ford is mainly used in "retro" hot-rod builds by builders more interested in a retro vibe and recreating history than performance. The spark plug may be sited over the piston (as in an OHV engine) or above the valves; but aircraft designs with two plugs per cylinder may use either or both positions.[5]. [18] The 1932 through 1938 motors used twenty one studs to hold down each head and are known as "21 stud" motors. The side-valve Flathead engine was never able to be as sophisticated as an overhead valve engine and yet it persisted in providing boring reliability. These conversions were not initially demanded by hot rodders looking for extra power, as they had not yet exhausted the capabilities of the flathead configuration, but were demanded by users of the engine in trucks and other such high load applications, where the constant flow of hot exhaust through the block to the exhaust manifolds caused the entire engine to overheat; the overhead-valve heads routed the exhaust out more directly, and away from the block. The bell is also compatible with the TKO 5-speed series. [11] The bottom of the block formed the parting line for the main bearing caps. Redesignated V8-82A in 1938, V8-922A in 1939, and V8-022A in 1940, compression, power, and torque remained unchanged. Simca then transferred the Aquilon production line to Simca do Brasil, where it was kept in production until 1969 (the company was known as Chrysler Brazil from July 1967). Despite having three rather than five main bearings, the flathead has stayed the course. The Modern Flathead Engine parts 9103 East Garvey Avenue | Rosemead, CA 91770 | (626) 572-0938. New Ford Flathead V-8 Engine Album 2 Volume Set Bk-13. [10] Sidevalve designs are still common for many small single-cylinder or twin-cylinder engines, such as lawnmowers, rotavators, two-wheel tractors and other basic farm machinery. [2] Note that on one pass the car broke 300 mph (480 km/h) but did not set a record. A Y-pipe took the exhaust gases to the right side of the vehicle to a single muffler, then to a single pipe out the back on the right side. [8] These new methods were patented. It was used by Simca in France until 1961 and in Brazil until 1964 for cars and until 1990 in the Simca Unic Marmon Bocquet military truck. One of the most important innovations in the Ford flathead V8 was the casting of the crankcase and all 8 cylinders in one engine block. https: ... And Why It DisappearedWhy Can't Pushrod Engine Rev High? The most complex part of the block was the exhaust passage routing. The engine maintained its position in the hobby well into the 1950s, even when more modern overhead-valve designs started coming out of Detroit. [20] In addition, rodders in the 1950s routinely bored them out by 0.1875 in (4.76 mm) (to 3.375 in [85.7 mm]). [8] The simple three-main-bearing crankshaft attached two connecting rods to a single crankpin, one rod from each cylinder bank. Flathead designs have been used on a number of early pre-war motorcycles, in particular US V-twins such as Harley-Davidson and Indian, some British singles, BMW flat twins and Russian copies thereof. The home of the Ford Flathead rebuilding specialist from mild to wild. ... Kirby became certain he could drastically improve Henry Ford’s venerable power plant to rival modern overhead-valve engines. It was in this climate that Ford experimented with V-8 tractor designs, some individual farmers converted their 4-cylinder tractors to Ford inline-6 or V-8 engines, and a few aftermarket companies offered such conversions for sale. Even today, people choose a flathead for period-correct builds over far more powerful options. Harley-Davidson understood this and in creating the KHK model they fitted that boringly reliable 54 cubic inch Flathead engine with a modern roller bearing crankshaft, sports cams and polished ports. As modern OHV V-8s became available and affordable in salvage yards, the Ford flathead V-8 rapidly disappeared from the hot-rodding scene. The water inlets and thermostat housings were moved to the front end of the heads, and the 24 studs and nuts that attached the heads on the old engine were replaced by 24 bolts. It was only used in Mercury cars, and heavy service trucks. For this reason, bank robber Clyde Barrow preferred to steal Fords as getaway vehicles. 1949-53 Ford Mercury V8 Flathead Engine Gasket Set Big Bore Best Brand Rs536g. [4] Most V engines of the time had multiple cylinder blocks bolted to a common crankcase (itself a separate casting). Even though V8 engines use more fuel than six-cylinder units, … To me, there's nothing that looks worse than a Chevrolet 350 in a beautiful Ford roadster. Sidevalve designs are still common for many small single-cylinder or twin-cylinder engines, such as lawnmowers, rotavators, two-wheel tractors and other basic farm machinery. Plagued by oiling, overheating and reliability problems in its day, the flathead was a nostalgic curio by the early 1960s. For example, some Dnepr and Ural used flathead designs that BMW had licensed to the Soviets. Although very small and compact, the D-Motor flat-six displaces nearly 4 litres. [18] [10], As with any V8, the block was relatively light for the displacement supported. [18] This engine was used through 1942 for civilian use and saw some use in military vehicles during World War Two. This engine was only in production from 1937 through 1938. In a T-head engine, the exhaust gases leave on the opposite side of the cylinder from the intake valve. Flathead News; Shop; Flathead Technical Info. Technical Manual Archive; Flathead Firing Orders; Engine Exploded Drawings; Transmission Exploded Drawings; Fuel System Exploded Drawings; Suspensions & Frames Exploded Drawings; Historic Photo Gallery. [8] Because sidevalve engines do not burn the fuel efficiently, they suffer from high hydrocarbon emissions. Alth… And by 1935 HP was increased to 85 HP. [15][16] On one pass the car broke 300 mph (480 km/h) but did not set a record. For powering the fuel pump, the camshaft is fitted with an extra cam located in the bearing on the flywheel side.[11]. [10], In a sidevalve engine, intake and exhaust gases follow a circuitous route, with low volumetric efficiency, or "poor breathing", not least because the exhaust gases interfere with the incoming charge. A compromise used by the Willys Jeep, Rover, Landrover, and Rolls-Royce in the 1950s was the "F-head" (or "intake-over-exhaust" valving), which has one sidevalve and one overhead valve per cylinder. The 337 features a 3.5 in (89 mm) bore and a 4.375 in (111.1 mm) stroke. [18] It produced 95 hp (71 kW) and 170 lb⋅ft (230 N⋅m). The originals still are. [18] The 1948 to 1953 engines have a revised cooling and ignition system. The Ford flathead V8 is a V8 engine with a flat cylinder head designed by the The sidevalve engine's combustion chamber is not above the piston (as in an OHV (overhead valve) engine) but to the side, above the valves. This engine was used in Ford's transit buses during the most productive years of the company's short stint in the transit bus business from the mid-1930s to the early 1950s, most notably in the 1939–1947 version of the Ford Transit Bus. Anton Pischinger (author): Die Steuerung der Verbrennungskraftmaschinen, in Hans List (ed): Die Verbrennungskraftmaschine, volume 9, Springer, Wien 1948. [18] This was done to provide a more powerful engine for the Mercury cars, which Ford Motor Company started making in 1939. [4] For example, the first Cadillac V8 engine was in that category. [12] Turbulence grooves may increase swirl inside the combustion chamber, thus increasing torque, especially at low rpm. A 136 cu in (2.2 L) V8-74[18] version was introduced in the United States in 1937. These shell main bearings are made of a cadmium silver alloy. Auflage, Springer, Wiesbaden 2017. The modern OHV V-8 powered vehicles available also contributed to the demise of hot-rodding's original culture (affordable modifications by working-class car owners), as new factory cars became capable of much higher performance than most hot-rods. A common conversion for the 1949–53 Ford cars and 1952–53 Mercurys was to block off the right forward manifold entrance and route the left side exhaust to a new pipe to form a dual exhaust system with better flow characteristics. Roy Nacewicz Enterprises Authentic reproduction early Ford fasteners. After WWII, flathead designs began to be superseded by OHV (overhead valve) designs. [1] A fascination with ever-more-powerful engines was perhaps the most salient aspect of the American car and truck market for a half century, from 1923 until 1973. It was introduced in the 1948 two and a half ton and three ton Ford trucks and the 1949 Lincoln passenger cars. [19], The 1948–1953 255 cu in (4.2 L), referred to as the model BG,[citation needed] was achieved by use of a 4 in (100 mm) stroke crankshaft in the 239 cu in (3.9 L) 8BA/8RT engine. The advantages of a sidevalve engine include: simplicity, reliability, low part count, low cost, low weight, compactness, responsive low-speed power, low mechanical engine noise, and insensitivity to low-octane fuel. In 1952 it was replaced in the Lincoln passenger cars and Ford three ton trucks with the Lincoln Y-block 317 cu in (5.2 L) overhead-valve V8. The sought-after crankshaft by hot rodders is the 4 in (100 mm) stroke Mercury version. Earlier Ford V8s had the unique Ford designed distributor driven directly from the forward end of the camshaft, which was an inconvenient location for maintenance. As with other crankshafts, static and dynamic balancing was performed (as this video on the Ford flathead V8 shows). However, not only was it was the first mass produced V8, it also introduced a … In 1934 a two barrel down draft carburetor was introduced. In the late 1940s, their aircraft line became unprofitable, but they found renewed profitability in aftermarket parts for tractors—transmissions, engines, and accessories. 8. More extreme modifications were to improve the airflow by removing material from the top of the block between the valves and the cylinders (called relieving), increasing the size of the inlet and exhaust passages (called porting), and by polishing the sand-cast surfaces to improve air flow. [17][8][clarification needed]. A lid made of cast iron covers the camshaft spur gears; the ignition distributor is placed on top of this lid and is driven by the camshaft spur gears. The main disadvantages of a sidevalve engine are poor gas flow, poor combustion chamber shape, and low compression ratio, all of which result in a low-revving engine with low power output[7] and low efficiency. The Ford flathead V8 (often called simply the Ford flathead, flathead Ford, or flatty when the context is implicit, such as in hot-rodding) is a V8 engine with a flat cylinder head designed by the Ford Motor Company and built by Ford and various licensees. With 6.12:1 compression,[18] horsepower remained the same, but torque increased by 2 lb⋅ft (3 N⋅m). One guy actually built a 700 horsepower flathead by reversing the intake and exhaust ports (how that's done I'm not sure) and running racing fuel. It's hard to overstate the impact that this simple little engine had on a whole generation of enthusiasts. Welcome to the web site of H&H Flatheads. Because the exhaust follows a lengthy path to leave the engine, there is a tendency for the engine to overheat. Part of the 1936 production and all production from 1937 to the end of flathead V8 production had both replaceable shell main bearings and connecting rod inserts (unlike the contemporary GM products), enabling straightforward and low cost rebuilding, another reason why the Ford was a favorite of amateur mechanics. He developed a passion for flatheads when he rebuilt the engine in his '47 Ford. Two passes have to be made in order to break the record. In US custom car and hot rod circles, restored examples of early Ford flathead V8s are still seen. It was a staple of hot rodders in the 1950s, and it remains famous in the classic car hobbies even today, despite the huge variety of other popular V8s that followed. Valves for each bank were mounted inside the triangular area formed by the "vee" of cylinders. In these applications, the use of an authentic flathead engine may be more important to the rodder or customizer than the potential drawbacks that are inherent in the design. [12] It also eliminated a complex oil jet system to feed the rod bearings in the oil pan. These advantages explain why side valve engines were used for passenger cars for many years, while OHV designs came to be specified only for high-performance applications such as aircraft, luxury cars, sports cars, and some motorcycles. [20], French-built 255 engines were fitted to the Simca Unic Marmon Bocquet [fr] (SUMB) light trucks of the French military. When these were decommissioned around 1990, they provided a new source of little-worn engines for the hotrodding community. Flathead engines produce significantly more torque than a 4-cylinder transmission can handle. These, designated V8-78, were offered with standard 6.2:1 compression aluminum or 7.5:1 compression iron cylinder heads, rated at 85 hp (63 kW) and 144 lb⋅ft (195 N⋅m) (aluminum) or 94 hp (70 kW) (iron).
