Where should I start?

If you're worried about gears put a set of 3.55's in the 8 3/4 and run a 275/50 MT radial, it's just over 26" tall. For the street run a pair of 275/60 radials.

About 4 years ago I went from 5.14's to 3.50 gears and only slowed down a half a tenth in the 1/8 and I was crossing the finish line in 2nd gear. Went from 6.34@ 108 to 6.39@ 109.
