You know, you do not have the best of luck iwth finding the right people. So to clarify, this guy that "rebuilds and races Camaros", inwhich racing them requires them to be in pretty much top running order to be a contender, right? So he rebuilds this motor and gives the car back with same problem it was presented to him with?
I have got to open a shop in your area, wow.
Obviously if the motor and trans/driveline have been reworked and the same problem keeps persisting, it HAS TO BE a a ignition or fuel problem and i still lean heavily on where we started 6 pages ago (dear lord) in this thread, the ignition system. If it were a fuel problem, the problem would be occuring trying to get the car moving not once it's up to speed.
Whew, time to check my blood pressure
