Rear Gears for Turbo 383 I need some help figuring out which gear is best for the S472 Turbo on a 383 through a Currie 9in to go with. Car came with 4.11 which is way to much. I am running 16lbs of boost. I was thinking
3.42
3.55
3.23 for the gears
The car is a 6speed car.
I have to change them out asap and get use to them before the big Ford vs Chevy shootout my way.

I run a 3.25 gear with a 28" tire through a th400. Seems to be perfect for my setup (car pulled a 1.34 60' last week). Turbos love the lower numerical rear gears.....I'm not sure whats the optimum gear for a 6 speed though. I'm guessing a 3.25 would be good for you also. The least amount of shifting the better.

I would think it really depends on how hard your willing to launch the car. My thinking is if your going to launch hard like 5K tallers gears maybe 3.23's. If your looking at 2-3K I would go with 3.42's or 3.73's

I launch at 6k now. I have been able to use a few different set up for tires. Right now 28in M&H tires.
