The truth about caltracs

I have stock leaf springs and have mine in the top hole with zero gap on both sides Rancho shocks set on 9 with Calvert front shocks. I am running 315 drag radial with 16-18 lbs air and I footbrake. My best 60 ft so far has been 1.34 and carry the front tires about 2 ft. off the ground for about 25 ft. I am running a D-50 truck that is extremely nose heavy. I hope to go to a 904 with a transbrake this winter, I do not know how it will work then. Pump gas 394 smallblock with mufflers and street legal, 2950 lbs.
