Edelbrock Performer vs Edelbrock RPM Airgap

It could have very little initial if it's a stock MP distributor.

Total timing is a rotten method for setting up a car.

If the balancer has marks you can read, you can still set initial and not be out of bounds on total. You know where it pings now, so you now need to find the point it still starts when hot or use a vacuum gauge method. Take that timing reading at idle, vacuum adv disconnected, and subtract the two. That's the mechanical advance you need in the distributor.

It takes work but cars run much better when initial is in a more optimal spot than most total timing set ups end up with.
