Please Note – this is NOT going to be 100% accurate. Numbers changed, I coulda mis-typed, but this is the best I can do as a back yard mechanic to help you out. This came from 3 different books, and I tried to put all 3 into one page for ya. Please look for the book CORVETTE BY THE NUMBERS for more accurate information. Thanks.
