Been a few years an I finally have my car running properly. Next up is a 9" rear end. I have an m6 and my car makes 335/330 to the wheels right now. I have plans of upgrading the heads and cam to make 400+ hp in the near future. I want a 4.10 gear but I don't want to run out of 4th gear in the 1/4 mile when I increase the power level. Should I get a 3.90 to avoid any chance of going into 5th gear before the traps, or should I stick with a 4.10? Lets assume traction is good with a 26 in tire. Thanks!
