Since I got the vette rally's I might go bigger on tires, so probly will go with more gear. The motors peak torque was around 2500, cruising at 70 was around 2k, and that was with 26" tires. I really want to run 295/50s, but I don't to spend money on new tires if they don't fit, so might go with 275s.
I'm gonna run Comp Cams Extreme 268, not a radical cam, slightly lumpy, but not extreme like a race cam.
