Here is a question for the brains trust

Can anyone identify this motor
It seems to be a strange number combination
right head c81t-bh
left head c81t-6019
Number stamped on right rear valley 12 with underneath b5102
On bellhousing sunken cast number 232
I can not find any other numbers
Engine number dosent seem right for a cmp engine

Andrew,
I repeat my response to an earlier thread: The C (Canada) 81T were heads used on the Ford trucks from 1938-1942. There should be another number other than the 232 on the bell housing. For more details see: http://www.mapleleafup.org/forums/sh...d.php?p=113873

Regards,
Jim

Jim, as mentioned in the other thread, the C81T heads were used right through to 1945, on Ford trucks, and Mercury cars and trucks. The specifications on the Van Pelt site refer to US civillian production, which halted between '42 to '45. We are talking Canadian Military production, which didn't stop throughout.

Andrew, the head marked C81T-6019, is it possible that the casting is somewhat rough, because the number should be 6049? Rub some chalk across it and post a pic! C81T-bh is an odd number, again a pic will help.

The 232 will be nothing more than a casting core number. The numbers 12 and b5102 stamped near the valley will be quality control inspector's stamps, and are often also seen within a square, triangle or circle, depending on the particular inspector's stamp. Rebuilt or reconditioned engines will have more of these stamps.

Ford engines frequently didn't always have an engine number actually stamped on the engine, although an engine number is sometimes to be found on the inlet manfold surface, the usual place for the engine number is on the gearbox bellhousing. The absence of an engine number will not be strange or unusual. You will have to rely on other ID points to identify the year or type of engine, such as bore size, distributor/front cover fitted, or even go into some internal details to be specific (such as crank pin dia. or number of piston rings), provided the engine hasn't been modified or rebuilt.

Thanks Jim and Tony

That is a good site to know about

Tony .spot on .just went and had a better look and it is 6049 on the head
Also had a look in the other spots you showed .Picture of locations very helpful
Nothing on the gearbox bellhousing .I did however find the number c11a-6520-c2 on the inlet manifold . I think it is only a part number though ?

looking around the cab i also found another b number on the front window sill on the passenger side .Would this also be a quality control inspectors number ?
