Default Gears?

I was just wondering what kind of gears would be good for my LT1? I don't know if my car has enough power for a 4.10 or if I should go with a 3.73. I have a 3.07 gear right now, but I'm looking for a lower one.

Thanks, Nick

I'm pretty sure you can't find a 4.10 gearset for your D36, and if you could it is too steep for a street driven auto trans LT1. Look into the 3.73's or even a 3.54 gearset.

3.54 or 3.75 a stall can help too.

I put 3:54 in my 91 coupe, and never looked back. Great off the line and top end. I'm thinking about 3:73 for my LT4 if I can find a deal.
Good Luck.
