Having 3.90 put in next week hope to be turning around 2600 to 2700 at 80 mpr. thought heavly about 4.10 but like to take trips durning the summer. Have a shop that has installed over 200 8.8 gears and plenty have been Motive gears with no problems, cost of $ 300.00 laber.

the rpm difference between 3.90s and 4.10s is 100 rpms, and these are not push rod motors they are modular, so for all you who say "this isnt a honda it shouldnt be revving that high" your wrong, they need to rev to make power
