chris42pu Wrench Fetcher C Joined: Mar 2002 Posts: 126 Fall Creek, Oregon	Trying to find information on the casting number on my 216. The truck is a 1942 3/4 ton. The number on the casting behind the distributor reads: R21846UTAH I have not seen an engine number like this and can find no info...I thought I already did this once but am finding it hard to decipher this. Thanks for any help. Chris Chris Simmonds 1942 Chevy 3/4 ton

Is this on the milled flat area next to the distributer and stamped instead of cast? Is this the same number on your title? You are looking for a number that is cast into your engine block near the distributor.

Hmmm...but yes, my silly mistake...this number is stamped not cast, right on the flat area behind the dist.. I will clean it up a bit better and look again. Thanks Chris Simmonds 1942 Chevy 3/4 ton

Thanks The original engine serial number would have been stamped, not cast in that same location. A replacement engine would have had no serial number, allowing the engine/block to be stamped when used as a replacement in a state that registered (and/or titled) a truck using the engine serial number. GMONIZ's suggestions seems very reasonable. What is the ID on your title/registration (it could be an engine ID/serial-number or the vehicle/cab ID/serial-number)?
