Flathead Engines

Pictures of a French flathead engine

French flathead V8 engine, made for French military through the 1980s. Surplus, new engines were made available to the public in the early 2000's.

French flathead engine. These were made for the French military up through the 1980's. The engine has late 8AB style heads but the bell housing is similar to the 59AB.

Front of French  flathead V8 showing distributor shaft cover, crankshaft pulley and waterpump pulleys.

The distributor is the later 8AB style. The water pump pulleys have different diameters. The crank pulley drives several belts.

Top view of the crank shaft pulley. You can see that the water pumps are driven by different belts.

Left hand water pump and bracket, presumably for generator.

Detail showing the lefthand (driver's side) water pump. I assume the bracket is for a generator.

Front of intake manifold of French flathead V8

Detail of the front of the intake manifold. On an 8AB engine, the crankcase vent tube would be here. Something similar seems to come off the right hand side instead.

Identification code cast into bell housing of French flathead V8

Trying to show some of the identification code cast into the bell housing.

Stamped identification plate riveted to French flathead V8

More identification numbers on a plate riveted to the engine, but the flash made the numbers unreadable (without the flash, it would have been too dark)

Rear of French flathead V8 showing oil filter, mechanical speed governor and revolution counter

Rear of the engine. In addition to the oil filter, these engines have a mechanical governor and a revolution counter. Remember, they were built for the military, not for racing.

Revolution counter on French flathead V8 engine

Detail of the revolution counter. No, I don't believe it only turned exactly 100 revolutions! But I'm not sure why it wasn't set to 0 either.

Exhaust manifold on right side of French flathead V8

Part of the exhaust manifold on the right side of the engine. These used dual exhaust (no crossover).

Exhaust manifold on right side of French flathead V8 engine

Exhaust manifold on the left side. Makes you wonder what sort of vehicle it was in. On American made cars (left hand drive), the steering box causes problems for exhaust headers on this side.
