I am having a problem with my Duster I cannot find for the life of me. 1970 Duster, 410 on toilet injected alcohol, 727 with 4800 stall spragless converter, 8.75 with 4.30s, Caltracs at 3/4 to 1 turn preload and shocks between 7-9 depending on the track. What’s happening is as soon as I let go of the transbrake it cuts off 3 times. When I foot brake it cuts off the same but only once. I have readjusted the suspension several times, checked the whole ignition system (@yellow rose), richened the fuel, leaned the fuel, unhooked the tach, unhooked the Digital Delay shift box, and chased all the wiring. The tricky part is it ONLY happens on the track. It will not do this on the return road, or in my concrete driveway. It’s something related to the hard shock of the launch, and it happens real quick.
