Hello, I can't seem to find a thread on anyone in a Coyote that has done 3.90 gears. If there is one please post link. But I already purchased a set of 3.90 gears for my Coyote. Current mods are cj set up, e85, full exhaust and tune...I'm currently on stock 3.31 gears in my mt82. How much of a difference would I feel from going to 3.90? I didn't want to go to to steep on 4.10. I mainly do roll racing and maybe occasionally track. Coyote is also not a daily driver. Would you say would I have an advantage in roll racing against other NA coyotes or no? Planning on staying NA.. Doing heads and cams next month. Thanks in advance!
