    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?
    Thanks

    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?

    My brother's 30k mile original Oct 72 built - 73 L82 Corvette has it's matching drivetrain - including a June or July 72 cast 0014 block which was machined at FLINT - the engine could have just as easily made it into a 73 Z28.
    The NCRS also stated the interchanging of 0014's continue into the 73 model year.
    This was done to ensure that Tonawanda and Flint castings could be swapped and machined in either location. Redundancy in case of facility shut downs in either location.

    I have a 3970014 engine block that I bought at the Carlisle, PA, swap meet many years ago that has a "E 16 70" (May 16, 1970) casting date. The stamping on the front pad is "T0518CRE" (Tonawanda, May 18th, 300 H.P. with T.H. 350 transmission). In the vicinity of the oil filter is the location of the partial VIN stamping "10N5?1710". I can not read the 5th digit because the stamping in on a cast surface. The "10N" part of the partial VIN is for Chevrolet, 1970, and Norwood. This block was therefore originally from a 1970 Camaro with L48 engine and T.H. 350 transmission. The block has never been bored out.
