i have an old willys jeep motor i would like to get out of my shed , after looking up the casting numbers which are 638632 which is and 134 cu. in. flat head 4 cylinder, this motor is complete from the fan all the way back to the clutch and bell housing minus plug wires and fan belt i do not believe this engine has ever been gone through so it should all be standard....make me a reasonable offer...
thanks for lookikng

Try to get a casting/serial no. There were a couple of different engines used in old Jeeps. They were based on the old Continental flathead designs, but some had a semi-OH valve setup.
The semi-OH that birthday Bob is refering to is called an F head. If a Willys guy asks that, and that's what the engine is, you'll need to know that terminology.
here are some pics

What you've pictured isn't an F head, it's the flat head version. Since an F head is half and half, they probably used the same block.
