my buddy Brian has 4.10's, Vortec SDS, headers, exhaust, and to date his best time is 12.9, he says the 4.10's are great for low end tq, but fall flat on their face in the upper RPM range. They might knock a tenth or two off your time, but dont expect miracles, he says he misses his top end.

The only issue on a FI car with the 4.10s is you had to shift to 5th (overdrive on the Mustangs) at about 112 MPH.

I know a couple of people running 12.8's with CAI, tune, and 4.10's and thats on street tires. I may go with 3.73's tho for a little bit of balance and maybe F.I. someday
