Currently 4:30 gears, 29x12x15 Hoosier slicks D06. 11.44 at 115mph. 3900 pounds (guess). I'll be working my way to hopefully high 10's low 11's at around 120mph. I currently go through the traps at 5900. I want to buy a set of Hoosier QTP's to run street classes with. Do I stay with the 29, or go to a 28 to get my rpm's up at the stripe a little? I know the rpm's will come up as my mph does, but that's why I'm asking if I should stay with the 29's or go to 28's? 528 hemi, 10.2 cr, 628 cam 295 duration, stock heads and rockers cleaned up a touch, stock intake with Vanke mods and a little cleanup, AFB's, 2 1/8 Super Comps to 3.5 colectors, 18" 3.5 pipe to Hooker Aero Chambers.
