69 GTX with 496. MSD Pro Billet distributer. The distributer will not turn any further to give the car more initial advance; it's at the stop. The car starts immediately with no issues and runs OK but it acts like it wants more timing. Your thoughts?

Can you explain what "it's at the stop" means exactly. Are you currently running the black bushing? Is the distributor hitting something that's stopping it from rotating any more?

Also, a lot of folks use the FBO bushing kit to allow for a greater restriction of the mechanical advance in the Pro Billet distributors, so you can run more initial without getting too much total advance. I am using the largest one in the FBO kit, which allows me to set mine at 22 initial, 34 total and I have it all in by 2000 rpm( the two small silver springs).

You may also want to coat the metal parts in the pro billet to help slow down the corrosion, and spend the time to phase your rotor in relation to the terminals on the cap.

I also drilled a couple large holes in the side of my cap to help get the ionized air out of there. I believe it contributes to the corrosion issue.

Pull the distributor and move the oil pump drive one tooth CCW, that will alow more distributor movement The Mopar factory service manuals says to bring the motor up to top dead center on the number one cylinder foring stroke and align the oil pump drive so the slot is aligned with the camshaft centerline Then install the distributor

By stop I mean the distributer will not physically move any more. It has been turned until it hits a physical barrier-a stop

You could move the wires one tower clockwise and reset timing, should give you a little more swing.

You'd need to turn the distributor CCW to get it retimed properly.

If you want more initial timing than most of the MSD bushing allow, I know a guy that is making a 10* bushing already flat sided and I have some 14* ones. They are about $10
