I have a procharged ram and it had 355 gears stock, and I went to 410 would 456 be to much for for me? I've heard 456 are the only way to go.. what would the rpm be at 70 on a 29" tire?
Found this chart somewhere. Gives you a good idea of what you will see RPM wise. The attachment is a screenshot and kinda small. It's at the bottom of this website. https://tiresize.com/gear-ratio-calculator/
4.56 gets you 118 and around 11.7 in 1/4 at 6500 4.10 gets you up to 135 and 10.3 @ 6500 rpm. So if you want the torque low 12s truck go 4.56 any faster go 4.10
thanks, I might go to 456 since low 12s to high 11s is good for a street truck!
