Here is a real stupid question guys. My car at 1000rpms is at 20 degrees advance. Now heres the funny thing... Keep the timing gun on it, and hit the throttle, and it retards itself!!!!!! I went down to like 12, if not lower. I did notice when we had the distributor out that the bushings in the centrifigul advance were shot, and the new spring kit I got the arms were backwards, and wouldn't fit. Would this cause the car to retard itself? Its funny, put a new set of Pro Line heads on, had them opened up, have a cam with .488 lift in there that starts to go at 3500rpm, and bought two brand new edelbrock 1405s for my dual quad set up... She feels sooo much stronger, and at 4000rpm really wants to run. Yet, with the old smogger heads, and piece of junk carbs, I ran 0-60 in .5 faster. And still, if I use my stall speed and brake torque to 2600 rpm, I still amd .4 slower in 0-60 compared to me hitting the gas and going. I am sure that this problem has to do with my advance.. Am I right?
