Anybody go from performer to an rpm air gap
translation: if you want to mess with the initial timing, shorten the advance. which means taking the distributor out and shortening the slots. They are not suggesting adding 9 degrees to the initial which would result in 41 total. That would be very bad.
Frankly, I don't think its causing the car to spin out of the hole or the lay down at the top. These are the two issues and I think the primary contributors to that are where you thought, chassis and intake.
