The car weight is 2600 lbs with me in it
wheel base is 94 inchs
rear tires are 32x14x15 with 7 to 8 psi in them
launching at 4800 rpm and torque stall is 5800 rpm
tranny is a 1.76 powerglide
motor is 383 sbc peak torque at 5300 rpm 525 ft/lbs
peak hp is at 6700 rpm 600 hp
car is 55 wieght to front and 45 to back
The other day i was playing with my shocks and tire pressure and my 670 foots went in the range of 1.38 to 1.42.......our track elevation is 2400 feet and usually corrected in the 3600-4200 range and as bad as 5300 feet
two weeks earlier i took the car to the coast and air was at 1400 corrected the worse and i ran 8 psi in tires and still would load and unload but not as bad with 1.34 60 foots.
So the biggest thing is should i loosen up the front shocks right up and tighten up the backs and go up with tire pressure and try elimanate the load and unload of the tires.....................thanks in advance
