Here's an attachment showing what looks to be all casting numbers of heads, blocks, & crank forging #'s. beerman posted that on a thread a few months ago, one of his first posts on this forum (thank you!)

So I picked up this alleged 1964 351C that a member said was in the tilt cab series of GMC big trucks, L series I believe. I wanted to check casting numbers to verify it wasn't a 305. Well... These numbers aren't on that list at all! 2457328 is it.
2457329 is a 401. 2457325 is a 305. This 2457329 is not listed, and the right front pad shows no serial number like my 305D does. I will sand off the paint further to see if any remnants of a stamping remain. Can anyone confirm what this is exactly? Supposedly a 64 351, members here said big front cover and fan off crank pulley means from a tilt cab big truck
