Not Ranked

I"ll throw my $.02 in ... I have 427W with 600 hp, 600 tq, TKO600 w/ 0.82 OD, 3.50:1 gears, 295/50/15 tires.

At 80mph i'm running about 2900 rpm, if memory serves. Its not pleasant on interstate driving and I get 12mpg if I'm lucky. Really wish I had gone with taller 5th gear.

Anyone want to swap this TKO600 close ratio with a TKX w/0.64 ?
