1973 vette. Is casting # 3970010 correct for L82? Thanks Ralph

Yes, and also correct for L48 and just about every V8 GM installed in cars and trucks throughout the 70's. Probably the most common SBC ever made.

Yes for the 4 bolt main. Don't know if the 2 bolt is different...

They had the same casting number as the conversion from 2 bolt to 4 bolt is a simple machining operation.
