    I'm going to look at a Willys F-Head motor that is on a pump,I'm assuming that it would be the same as one in a cj-5 ,are there any differences like crankshaft end or bell housing mounts....Jim

    I can tell you the f head industrials had lower compression then the engines used in vehicles. I would assume the same for a F head.

    Check to see if there is a provision for a pilot bearing/bushing in the flywheel end of the crank. I got a reground crank once and there was no pilot recess!
