I'm thinking it was above 8000 RPM in the 1/4 mile shruggy
I was told that it had 5.38 in the rear when I bought the car and when my poor little 505 C.I. 400 block bracket motor had it tongue out at the 1000 Ft timers I found out why after pulling the cover to inspect the gears shock
It likes the 4:56 with both the 15x33x15 Goodyears and the smaller 14x32x15 M/T stiffwall up

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
