Will..with 4.10s and a 6200 rev limit you will max out in the 1/4 mile early, somewhere around 117 mph in 4th. You have a couple of options. Throw a cam in there with some good springs so you can raise the rpm range to 6700 rpm or so with 4.10s, that will give you around 126 mph in 4th. Or you could just go with 3.73s and nitrous. that would give you around 128 mph.
