...not a flat head..looks like a V8.
flathead v8
It is a flat head V8 Ford engine. Called a flat head because it doesn’t have overhead valves, the valves are in the engine block. Hence the name flat head, applied to all engines of the genre regardless of how many cylinders they had. Note the spark plugs are in the head, no rocker arms, no valves, no push rods are in the head.
