Am running a 496 chevy in a 225 hardtail. Glide with 5600 stall 4.30 gear, new Hoosier 33.5X17X16. on poor tracks 60 ft is 1.17. went 1.14 today, ran 7.95 @ 166.78 on last pass. Running tires at 5.6 psi. any thoughts on launch RPM or tire pressure? 60 ft is the same leaving at 3500 or 4100. thanks much
