Casting number locations

Hey Everyone Im having trouble finding some engine block numbers I think one engine is a 400 and the two other engines might be 307 but i cant find the casting numbers on the block. Does anyone have any ideas were the number might be on block?
Thanks much

Re: Casting number locations

SBC Chevies I think were all on the RH side on a casting piece that extends past (forward of ) the passenger side head. It would depend on the year whether it is behind the alternator or the AC compressor... Typically you have to remove the Alt or the A/C compressor to see it...

There are some numbers also often cast into the rear housing where the Transmission attached... Third gens typically have 5.0 or 5.7 for example...

Re: Casting number locations

on the bell housing behind the driver side cylinder head will be a series of numbers(7 or 8) that is the casting number. there will also be a date code casting to the right of that. the numbers on the pad in front of the pass side cylinder head is the production stamp.
