What gears to get? I'm pretty sure that my next mod is going to be gears. But I don't know whether to get 3.73s or 4.10s. My car is a Daily Driver and really doesn't need to lose any mpg. Would those gears affect my power from a roll? And what would be a good company to get the gears from?!?

im thinking of doing the same thing. i know with my car (and the newer m6's) they have 3.42 gears in the rear. stepping up to a 3.73 should be slightly noticable, but not anything rediculous like dropping chunks of time off ur ET. go with 4.11's. you'll probobly drop about .25 sec off ET if driven correctly.
oh yeah, LT1 + 4.11's = torque monster

I put in 3.73's and have been really happy. Didn't lose any top end really and it took away all that lag. I always jump out on bolt on LS1's too that don't have gears. My friends with LS1's with lid, longtubes/y pipe and exhaust have a hard time pulling away from my bolt on LT1

Yes they will affect your car's pull throughout the powerband at any speed.

Plus I love the way they feel on the highway. I don't run out of gear too fast.

Get 4.10s if you plan to stay all motor.
I have 4.10s in my car and I absolutely love them...until I got to the track with nitrous. Going to 5th in the 1/4 sucks! They are PERFECT for all motor though...around town and at the track.

got about 2 seasons out of each on drag radials... and a 6 speed
The actual strengths of the ring and pinion are minor differences. The 3.73s are slightly stronger, but I promise they're no more resistant to breaking stuff. TRACTION is what breaks these rears, not gear ratios.
And yes, it changes the way your car pulls for the better.
