I have read every post on this site about CALTRACS, and have come to the conclusion that no two cars are the same,even if set up nearly identical! I have a 1974 DART sport,360 stroked to 410c.i. making 600hp @ the flywheel on the dyno,727w/5500stall,4:30 gears & weighs 3300lbs with me in it running M/T et street radials. With the 40year old stock springs & slapper bars my 60ft. times were from 1.47 - 1.50. I went like a fool & bought caltracs,monoleafs & thier rear shocks . I have tried every possible combo of settings, up & down on launch rpm,0 preload to a 1/2 turn,every shock setting, as low as 13psi tire pressure, even top hole with no improvment. The best 60ft. I can get is 1.54. I have talked to John Calvert himself several times & all he can say is its not his product! Its the track, my tires, transmission, converter, carb. , even the driver(me). I have the full travel on the front he suggested +(5.5inches) everything free & not binding. I have concluded that caltracs are for fords & chevys & are useless on a mopar! If anyone can supply a solution on settings, other than whats on this site, please do so. Otherwise I will be removeing this crap & returning to my stock suspension! As a side note I have several other mopar racers i've spoken with who are also unsatisfied with thier caltracs! :banghead:
