Nicks Garage, 572 HEMI, Here we go....
Unless the programmed timing curve is set up for full advance before about 2000rpm, he has no idea what the actual full advance timing is.
He never checks the timing at high rpm(not that I’ve seen anyway)
After I’ve tightened down the distributor, I give the motor a good zing while watching the timing light so I know how high the timing really gets.
