Thank you. It always helps to ask someone who knows more about a topic. I especially appreciate the wisdom that using the right book makes a difference. With your input above and some further research on the GM Heritage site, I was able to confirm that the engine (maybe not the head) was made in Flint in 1952 for a Chevy model 3800 truck. Moreover, it appears that the serial number in the driver's door frame seems to confirm that the truck was made in Janesville as a Chevy 3800 in June of 1952. It seems I may have a largely numbers matching truck afterall. I want to thank everyone for their help. Now to find out what's wrong with the engine.

Sincerely,

Jim
