[quote=GY3]Nothing with that combo.

We run a 3.54 gear with a 505" stroker and rear ratio seems to matter very little with the torque it makes.: I ran 4 different rear gear ratios in my old pump gas stroker motor in my Duster, 3:73, 3,91, 4.10 and 4.30 with no other changes, other than running at different tracks. It ran within.08 and 1.0 MPH as long as it didn't spin
I did have a Mopar brand low gear drive set (2.77 I think) in the 727, best 60 ft was 1.42 I think
