Need Help Setting Timing, 93 Mustang

Let me guess: you bought the car from someone else and didn't do any of the work we see...
The wiring looks like a commercial for a girl with frizzy hair - an explosion in a mattress factory. No telling what has been done or how it is wired.

It looks like someone cheaped out and used a EFI distributor. There is no mechanical advance, and no way to advance the ignition timing without a computer. The ignition timing is set at the base setting and never advances. Locked timing is costing you performance and economy.

You're going to get to make a tour of the online auto parts store catalogs and find a truck distributor for a 351 made before 1986. It will be a unit designed to work with the DuraSpark ignition that originally came on Ford trucks. It will have an electronic pickup and a mechanical advance and a vacuum advance.

So my timing should be looked right now, i put a timing light on it last night and revved the engine at the same time and the timing marks seem to be moving when doing so. Does this not mean that it is advancing on its on?

If you have no advance I am pretty sure it shouldn't be moving.
