After reading all of the posts, visiting each link, and collecting all the numbers from the block, I think I have decoded the engine in my 59 Chevy 1/2 ton Napco. It appears it is the wrong motor.
Please take a look at my conclusion and let me know if I am right or wrong.
Block casting Code - 3769716 = 1960
Block date-casting Code - Con 4 G60 = July 6, 1960.
Engine Stamp Serial # FO 707A = Flint MI, July 7th 1960.
Head Casting Code - 3836848 GM 30 = Number used for several years on 235.
Head Casting Number - B59 848 = February 5th 1959 ?
While it is a good running motor, if it is the wrong one I will probably be looking for a correct 59 engine. I am also confused by the fact that the throttle linkage seems to attach in a different location than my other 59, requiring the rod to to be shorter. I will need to modify linkage to get it to work.
Once again your input and opinions are greatly appreciated and I look forward to responses.
Thanks,
Brian M
