Rear End Gears 3.49 to 3.73

[Excaliber]

2.95 is better than being in the 3's for sure. I think my TKO is 2.87 with my 3.31 rear gear. It's in the ball park, but I would prefer something like a 2.7 first gear, just a touch higher but not much.

Of course a lot of the final gear ratio selections have to do with a couple of factors. What cruise rpm do you want at a typical freeway speed, 70-75 mph. 80 will get you in ticket territory for many states. And torque and horse power play a roll as well. Lower gears can be more fun, BUT, if your running a bunch of horses/torque it aint so fun when it's so hard to control wheel spin and the car is more likely to get sideways when you least expect it.

A 2.95 with a 3.9 rear gear would be a disaster for my engine. First would be so low I'd quickly get tired of having to shift so soon (20 mph maybe) around town and would be tempted to just use 2nd to take off. On the drag strip there is no way I could hook that up. I AM running slicks already and can barely control wheel spin outta the hole with my current gearing!

2000-2200 at 80 mph wouldn't work for me. To fast for cruising in Oregon!!! Yet, I HAVE to keep my engine in the 2,000 rpm range minimum or it "bucks" and tends to load up the plugs. So I went with a .82 rather than the .6 over drive.
