I'm starting to warm up to the idea of the 3.27. It gets me very close to my goal of 2000rpm at 65mph.I would consider a 3.27 or 3.55 rather than dropping all the way to a 3.08. A 29" tall tire with a 3.27 rear would be the same as your stock tires on a 3.08, but stronger. Or a 31" with the 3.55 rear would be close to your goal...or if you want to keep your rear (bad idea since it's a 7.5 anyway) you could run 3.73 gears and lower your rpm to your goal with some 33" tires.
Of those options I think the best is the 3.27 w/ 29" tall tires. It'll look better, drive better, still have cheap rubber (things get expensive once you get 30" and bigger) and have a stronger setup vs a 3.08 rear. Too much larger on the tire and you start losing mpg as well. Although a 31" w/3.55 wouldn't be too bad if you like the bigger rubber.
3.73 - 2350rpm
3.27 - 2060rpm
3.08 - 1940rpm
I'm not concerned about torque output while driving....I am getting more worried about whether or not the 3.08 will survive however.
Do you have any recommendations? I'm not too crazy about adding more complexity to the drivetrain than necessary. Plus I'd have to recut and rebalance my driveshaft.What about an overdrive unit? You can switch it on and off when needed, giving you better torque, or lower RPM.
