Help with gear ratio

[Rick8896]

I have a 84 Olds Cutlass Supreme. The car is stripped, about 2900lbs.
This is a new build.
355cid motor, 10.5 to 1 comp. full roller motor,Hughs Powerglide w/ trans brake, Hughs Pro II converter 4500 stall, Ford 9" w/ 35 spline axles, MT ET Drag slicks 28x9.0x15.
It's time to buy the 3rd member. I would like to get in the 10 seconds at the track.
Was wonder what gear ratio you guys have and/or recommend.
Thanks
Rick

Check out some Drag calculators. Just a guess 4.10 gear.

Depends on how many ponies you have and how hard you are going to turn it. Use the Wallace calculators.
