I'm ordering my new rear end gears this week (Trak-Loc unit . . . $450 rebuilt), and have my choice of gears, and only want to do this once . . . .
And, so I've asked here on the VMF, and checked out a few calculators online, all with slightly varying results ::
online RPM at MPH Calculator returns results I'm happy with (my tire diameter is 24.9 inches, 4th gear trans ratio is 1:1).
What I'm looking for is "What rear-end ratio is going to give me good 'get-up-and-go', but still allow me to drive at 70 MPH on the freeway, and not let the engine sustain high RPM's for extended periods of time"??
I've got a 3.25 now. I was thinking of going with a 3.00, but now I'm thinking of going with a 3.50 (the "calculator" shows me at 3300 RPM at 70 MPH with the 3.50, which doesn't seem too detrimental for sustained periods of time).
What do you guys think?? (I know I've asked this before) But . . . 3.00 gears?, or 3.5 gears?, or stay with the 3.25?? Anyone with more experience with rear end gears than me?? (I have none :p)
