Hi David,

Welcome to the forum! Always great to have new members onboard and to hear that another Ford CMP truck has been saved from extinction.

I cannot offer any info based on the s/n but a photo of it would help to identify it.

As a general rule, the raised casting number and letters on the right front side of the block and/or the bell housing will give you the date the block was cast. If you post them I can identify it for you. It would be something like "C..9A"

There are some Blitzes around that have been retro fitted with earlier 21 stud motors which automatically rules it out being the original, likewise the later 8BA engines with the separate bell housing, top mounted distributor etc.

Car engines were often substituted for the truck engines over the years so things like single sheave pulleys on the crank, water pumps, and generator indicate a passenger car engine. A 1944 CMP truck would have used double row pulleys.

Hope this point you in the right direction to get an answer.

Cheers,
