What gears do you guys have?
What set in your opinions would be best for cruising and racing considering having a 350 TPI setup stock or even moded.

I'm going to be running a 3.73 gear set in my Z28.I've got a modded 350 and a T-56 though.The car is sitting on 255/40/17's So if i remeber right it works out to a 25" tall tire.

What tranny are you going to be using?

If you haev an auto ...go 3.42 . If you have a 5 speed , go with 3.73. I have them with my 353 5 speed setup and I love them.

Do NOT go with a 4.11. You have a TPI with an auto, just as said by D above, don't go higher than a 3.42. If you have 9 bolt stock 3.27, just leave it. The only aftermarket gear is 3.70. Go with a convertor for the trans or something, it'dd be money better spent.

4.11 in the 9 bolt here, haven't tried it yet, should work good. I think neil is going with either 3.73 or 4.11 in his 9 bolt as well. They actually have quite a variation in gear numbers for that rear, if you know where to get them, which I don't.

Thanks again neil.
