Back in the day I went from a high h.p. 455 cutlass to one of these. I felt like I went from 0-5 in 4 minutes lol. I didn't own mine much more than a month. I searched high and low for my cutlass d.d. And never found it. So a 79 z28 was the best thing I could find. That turned me back on to the first gen f body again
