Thanks for your reply. I feel that the info that I gave you is solid and will give you something to work with. I run 3.70 and 3.90 gears in my gas burning Beretta that runs 187 MPH in the 1/4. The 3.90 will be nice for a torquey combo and you won't be over revving ant the stripe concidering your main use of the car is not heads up. Good luck with your project, it sounds like it would be fun to drive.
