The last 4 speed drag race SB 340 car I drove at the track was a 1970 Duster with a set of 5:57 rear gears with a 3.09 first gear NP833(17.21 SLR, let the clutch out at 7000 RPM and shift at 7000 RPM 3 times very quickly ), you were real busy the first 400 to 500 feet or so with that car
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
