4.10s or 4.56s

My 2 cents; at least 4.88's, more like 5.13's, if you are mostly racing 1/8th mile.

Some thing to think about:


I also race 1/8th, same size tire, a M/T 275/60x15 drag radial, I've run 6.98@ 97.02, with 4.88 gears in the back, I was turning 5680rpm when I crossed the stripe. The car is a 65 Barracuda, with a 360.
