Hey everyone,
I'm about to swap gears in my 68 Dart from 3.55 to either 3.91 or 4.10. I'm trying to decide which I should go with. This is going to be a 50/50 street/track car with minimal highway driving so I'm not concerned about my highway cruising rpm.
Engine is a 408 stroker
Tires are 28 inches tall.
Trans is an A833 with 2.47 1st, 1.77 2nd, 1.34 3rd, and 1:1 4th.
Max rpm I'm looking to spin the engine to is 6200
My two questions, what gearing and should I be planning to shift into 4th or leave it on the rev limiter in 3rd (I feel like that won't be a good idea but I've heard people say that so I wanted to ask).
