Stall Speed vs. 60 ft. I know that tire/traction differences will come into play here, but I want to see what you guys are getting. The best 60' I have cut since the th400 is a 1.79. My converter is a 3500. I haven't had a chance to spray it yet but I was wondering if my hopes of low 1.6's/high 1.5's on motor are out the window. I am on MT 325's and for the record I haven't been to the track on a very warm day.
Thanks

Have not tried my E/T streets,YET.
Old set-up:
Vig 3600-E/T streets(same as above: full weight etc..)
1.74 on motor
1.54 on spray

I think it's less about the stall speed than the STR. The short
times are about acceleration at low speed, which is torque
and torque multiplication. I see most low- to moderately
modded cars as having near flat engine torque from 3K
on up to where airflow starts to fade. So I don't think 500
RPM give or take will make the same difference as a 1.8:1
STR vs a 2.7:1, not uncommon in 4000-range converters.
Provided your tires stick that's a 50% increase in rear wheel
torque over stock, on top of any gain from being in a better
torque position.
On the negative side in this case the TH400 has a pretty
short first gear, way less than the 4L60E if memory serves
and this cuts back on your bonus.
