I have a 2.56 transmission that I run 2nd gear, 8x 22.5x 13r hoosier tires ,and have a 3.45 rear gear in car as of now and I'm getting left behind ... What would be a good combo tranny and rear gear? Also have a 2.14 transmission. And rear gears I have 3.08 and a 3.27 ... Or do I need different rear gears ? Any help will be greatly appreciated... Thanks for your knowledge and posts in advance
curious to know what tranny you have that has a 2.56 2nd gear ratio

Im thinkin you need to check your final drive..Never heard of a 2.56.. Love to have something that low though!
Had a friend look at it , he said it is a 2.34 transmission.
That's a T5 trans (87-93), same as I use. So u actually have a 8.07 final ratio. Are you getting "left behind" because your screaming the motor at the flagstand or is it just not accelerating? I agree with that gearing & 13" tires on a 3/8 track you could hit 10K on the tach.
If your engine can safely hit 8K, I would use the 3.08. JMO.
I would try the 3.08 rear gear with your tranny in the car first. If that's still too much gear then go with the 2.14 trans and 3.27 rear gear.
The SROD with the 2.56 second gear you could move to 3rd gear and run a 3.73 or 4.11.
I run a 3/8 track too. We run the 214 trans and a 345 rear.
