What Gearing in T/S

The motor will be built for Nitrous if we decides we want to use it.But we are not going to use it at any Divison races plus we will Bracket race it to..Maybe at some Local races like 4.70 classes or something like that we will try Nitrous..We are just looking for 4.90s to 5.0s 1/8 mile if it runs faster great.We do not plan to run any National events because the bumbs spot is so fast for us..
We will run are 10.90 car at National Events.

Just looking for a gear to start with on all motor.

If you want to do the math this is the web site with the formulas you need http://www.golenengineservice.com/html/calculators.html .
most of the Top Sportsman gears I have set up are 4:33. but most use nitros so do the math and don't overestimate the rpm potential of that 632.
I would gear the car fo the quarter because if you add more gear for the 1/8 mile you will lose some consistency.

Good luck
