I sure would like to feel the difference between my 4.10's and 4.56's. If I ever drive my car on the highway less and decide to not get a supercharger I might wind up switching over, I bet it would make it feel like an animal.

I don't think he'll see 11s just yet. But Im sure very low 12s are in the works.

12.577 @ 110.36, 1.82 60 ft. I made several passes, this one was the best, I'll scan the two best and post them, I can now say I need upper and lower control arms as the wheel hop is bad, they must be gone as I couldn't even spin the tires in the water box without wheel hop, DA was 5071 at the time of my best run, even the new 5.0 were trapping low, (107 was the best) I even got to beat up on a 2010 Shelby GT500, his best trap was 108. according to the DA calc. http://www.dragtimes.com/da-density...77&mph=110.36&correctetmph=Correct+ET+and+MPH
my car has a solid hi 11 run in it a sea level...

and for anyone that wants to know the 4.56 gears are way better on the street and freeway then the 3.77 I had in it before. 65mph= 2500rpm's, 75mph=2900rpm's

Not bad...4.56s it is for me then
