My car is actually a 4 speed car, but has only had one in it under my ownership(since 1981) for a very brief time.
I never had “good” stuff with the 4 speed.
And the motor was very mild back then as well.
I had one outing at the track with the 4 speed........ probably like 1984-ish.
3.23’s, regular radial tides, slipping clutch....... no headers on the motor.
It was something like a 13.86@101 after figuring out how soft I had to leave to not fry the tires.
I’ve made some passes in other people’s cars with 4 speeds before....... nothing real fast though.
One of my friends has several FAST cars with 4 speeds.
He let me run his 71 super bee with a 493 6bbl in it one weekend.
With the stock type bias tires you have to launch pretty soft....... 60’ times around 2.00.
I think I ran a few 12.0’s with that......at around 120mph.
