    I have had one of these "014" blocks in an SS before and have run across a few since then. They came in 2 and 4 bolt mains between 70 and 72. Anyone have one of these that came original in your documented Camaro?

    My 70SS has one that is original. This block was basically the same as the 3970010 block . Tonawanda used mostly the 3970014 block while the other plants used mostly the 3970010 block for their engines. Chevy usually had two similar castings most years that they could interchange if there was a production problem with one of the castings. That way, production couldn't be halted due to a failure somewhere. They did the same thing with the heads in 1970. There was a mix of 186 and 041 heads.

    Can you read the date code on the rear of the block?
