My car peaks at 6800 rpm,So anything higher than that does not do me any good. I went slower with the 4.56's in the same car, I was at 7400 at the traps, Way to much for this engine set up. I have a 415 car that does not like the 4.30 gear, Its very happy with a 4.10. With the 4.30 11.0's. With the 4.10's 10.85.I shift the car at 7400 end up at 7100 to 7200 rpm.
Yes I still use 1th gear, It's fun.
