I thought this was a useful little table with a couple good formulas:

Hmm, Now I'm thinking if I ever do a gear upgrade I'll go 4.88.

Holy hell...why would you do that...what gears do you have now and what size tires are you planning on running? I run 4.88's in Red, given no OD, but if you're running 31-33" tires...I think 4.88's would be a bit of overkill if you ever planned on hitting the highway again.

31" tires,x 4.11 gears = 2896 RPM ( near factory ratio) My ***.
It won't do 65 mph with out sounding like its going to fling things

Yeah, I was wondering a bit about that chart, I went to 33" under more power lol.

Its right my 72 sounded pretty hairy at 65 when I had the little tires on it I looked at my tach and it said 2900.
