If the car in the pic is the one you are trying to get to launch, first thing I would do is get the back end down!!! I don't think an instant center plot would even register with the rear that high static!!! How much rear end drop are you getting? Besides the Cal Tracs, what is the rest of the rear suspension??? Also what tires are you running and what pressure are you running in them? 60' time is slow, are you sure the converter has flashed when you launch? Maybe just some converter slippage killing the 60' time....
