Re: LS5 long block value?

According to Colvin, the "512" block was the only Chevy block used as both a '69 427 and '70 454, since GM had already made the decision to increase the stroke for the '70. This casting was also made with both 2 bolt and four bolt mains, and used in the big Chevys and 'Vettes in '69, and Chevelles added in '70.
