I think the only time that the F Body was not just as fast (Quarter Mile) than the equivalent Y body was for Gen 5. Gen 1, 2, 3 and 4 all had roughly the same hp (other than the 5 advertise hp GM had to deduct from the F Body to make Corvette owners happy) and roughly the same weight and the advantage of a live rear axle to put the power down.

Gen 5 is when the engineers missed their weight target by more than a few 100s of pounds and the F Bod became mostly a hog.
