My Swinger has a 408 W2 @ 500+ hp and a 4sp. I got say that “beating on it” on the street is not possible ( advisable) unless I am in the middle of nowhere on a wide street! And I don’t think I have ever hit 6000 rpm . Lol
Even with my M/T drag radials muchless my 14” stocker looking wheels . And my car launches pretty straight .
Maybe if I lived in the country ?
