How would 4.30 gears and a 4l60 trans be for a c/i/h only vehicle. I figured a 28" tire would be needed but can this be a good setup or not? I can get a killer deal on a gear, but idk if it will hurt my engine or not.
What stall would I need for this setup as well.
Its a nitrous car and shifts at about 6700rpm.
any help would be greatly aprreciated

It should be fine if your running a 28" tire.

28s and you shall be good. A buddy of mine has that setup and is deep in the 10s with a small shot.

I think the 4.30's will be a little too steep. They would work nice on motor but a little too much for the juice especially if you want to cross the final trap @ 6700 rpms. How big of a shot do you plan to run? Most nitrous guys run 3.89's and that seems like it would better suit you @ the 6700 rpm mark.

You should be running out of gear and most likely will need to extend the RPM range which is a KILLER for the 4LJunkE so I would run a calculator. You on ave get 1" of tire growth which will help but being a auto there is some RPM slip.

It would be nice to give you a clear cut answer but to give you a reasonable answer with any thought behind it we really need more info. I'd like to know what mph and rpm you're currently going through the traps at on nitrous?
What gears are you currently running?

radial or bias?

Is this 1/8 mile, or 1/4? If it's 1/8 mile I would say go for it, but 1/4 might not be a great deal. What gearing do you have in it now?

Need to know MPH to even begin to guess.
