Check the numbers on the crank, the 302, 327, and 350 share same block specs.

The 302 crank will have an 1178 casting #. On an original block there will be a stamp on the front passenger side that will end with DZ. e.g. V0130DZ. Will have a 4 bolt main with a windage tray, dome pistons.

Check the casting date on the block. If it still has it's DZ stamp this will help determine if it's been restamped. The 010 block was first produced in April of 69 and lasted til 1979 (maybe even longer) in different configurations...

This block (3970010) seems to be the one of choice for replacement engines. I've seen it used as part of the display engines at several of the chain auto parts stores such as Pep Boys.
