I dont know if I'm hijacking this thread by asking as question... but this topic has caught my interest..

My Duster is a true street car that I race alot.. Currently its 3180 lbs plus driver, 727 reverse, 4.10 gears with 28.0" tires..

I cross the line at 6800 rpm and cruise the freeways at about 3500 rpm... The stall is 3500 and the flash is right around 4400 rpm..

The car will 60' in the 1.6x range and the last variable is the gearing in 1st gear, which I dont know..

My question is this.. What would happen to my 60', 1/4 mile ET and MPH.. and lastly what would the freeway cruising rpm be if I was to convert to a 3.23 or higher gear?
