Launch rpm for F/S. 396 ,325hp ?

IMO If you've got it dead hooking keep raising the launch RPM's until you get about 1 full revolution of the tire. Then tire making adjustments to the clutch, chassis, tires, shocks etc... to get it to dead hook again at your new launch RPM once you get that then keep raising the launch RPM again until you get your 1 revolution back. Obviously the time slip (60') will be your guide. Just my .02
