Look in the 3.70 range and a 28" tire.... but every car is different...

it'll also depend on the amount of converter slip that setup will have. I would go 3.70's just to play it safe. If you still want more gear, you could always step it down to a 27" tire.

Figure out where you think the car will trap, max RPM for the engine, and what size tire you're going to run. With the little info you posted, I'd guess a 3.73 with a 28" tire and 3.55s on a 26" tire. This is assuming stock cam.

You can run as much as you would like dry... I wouldnt try to do it on a stock fuel system at all...
