Coming in a little late on this thread. Here is my 1972 - got it back in 1990. Its been together and apart more times than I can remember. This time around, its first big block (482). Was almost 800hp on dyno and when we had it in my friends chevelle (tube chassis car) it got into the 9's. Probably low tens in the nova (small tire 10.5 and stock body with 10pt)
