its a 427 trex, drag ported, 39 pwks, alcohol, 1-6 full override, stock clutch basket crank gears, and im runnin 18" tires. Its all i got, that will be the first upgrade(taller tires and american racers) The best time ive ran so far is a 7.4 @90mph with that setup. I have no idea as to what power its making and yes im a heavy rider :biggrin: 255-265. My 60ft is where im the worst, on that pass i believe it was a 1.86.
