Default Re: Need help with pro tree reaction time

Car specs:
107"wheelbase
522 bbc 840hp
pg with 1.80 low
4.30 gear
33x16 D1 Goodyears
4-link/swingarm
strut front
23" front tires

Car runs strong & straight, 8.40's @ 160, 1.20 60's, but will barely lift the front off the ground. Great bracket car, but mid teen lights if I'm really on the tree, just aren't competitive in SG. Any suggestions?
I agree with everything topspeed said. I myself would run a stiffer sidewall rear tire. Most of the D-1 are soft sidewall. You'll also need a 6000 to 6500 stall converter. Change one or both and you'll see dramatic changes.
