Gearing Q?
Gearing Q? Hey Would Y'all think that having 4.10 gears w/ an M6 is too much gear considering i have a single T-76 going into the car. I know it will get me spooled quicker becasue my revs will be higher at lower speeds but how does it effect traction.
I know it's already going to be an issue since i'll be at about 16psi on pump gas. Will the torque multiplication be too much to use on the Street?

Yes, waaaay too much if you are running 16psi. You will be out of gear before the end of the quarter by a long shot if you are running that much boost on a t-76. I'd leave the stock gearing in there with that much power. You'd be quite a bit over 700rwhp with that much boost. Especially since with 4.10's 1st, 2nd, and 3rd will be absolutely useless on the street on your setup.
Keep the longer ratios in there, you have the power to pull them, and you'd stay in gear longer making the boost work for you more; rather than having to shift all the time and losing boost between each and every shift and only gaining nominal speed over the range of the first 4 gears.
Big powered turbo cars like long gears, makes for long and hard pulls. The longer gears will also load up the turbo better, getting you to your targeted boost level easier.

Ditto....I have a 408 w/ Procharger D1SC pushing 13-15PSI and 4.10's.....it's useless and a bit scary if your on a narrow back road. Like said above 1st thru 3rd has basically no traction. And you'll be hitting the 1000' mark and be out of gear on the track, unless you want to be the first one to shift to overdrive in the 1/4. 
I just recently bought a set of GM Superior 3.42's to put back into it. It will numerous advantages over the 4.10's cranking the power out that we are.
