And as one story went they were stored in a damp warehouse which lead to the blocks needing to be bored ...chevy did run alot of 402's in cars badged 396 because of the great sucess of the 396 ( don't mess with sucess ).....anyway 396/402 are great blocks and should be able to go another .060 no problem...........or throw that crank in a 454 and injoy your 427
