confused 79 Pace Car timing

Is it possible to have the distributor turned the whole way clockwise and the engine still starts and runs? Could this be caused by the timing chain being worn and jumping time? It is a 302 stock and has over 100,000 miles. I guess this may be a dumb question. Any thoughts on this?

For a timing chain to jump that far , it would have to be battering it's brains out . If the timing was that much out , if it ran at all it would running like a dog .

Re: 79 Pace Car timing

Its 2 years later and the engine still runs good but it has gotten hard to start lately. I recently set the timing right on the mark and for a while it started like normal. Now lately it doesn't want to start. The other day I tried moving the distributor clockwise pretty far and it started. Then I put the timing back on. I have never replaced the wires, distributor, coil, etc. Does this sound electrical or possibly timing chain?

Hard call, really need to put a timing light on it and see if it walked.

Re: 79 Pace Car timing

If the distributor cap, rotor, plugs and ignition wires are as old as I think you are saying they are, you should start with a complete tune up. See how it runs after that.

If you are still having problems, you can check the camshaft timing, and cam chain wear, by removing the valve cover and checking valve lift, while turning the engine over with a breaker bar and using a degree wheel to check crankshaft position.

That's easier than it sounds, and easier than removing the timing cover with the engine in the car.

BTW, ford used "plastic" timing gears off-and-on during those years. They were not as durable as steel.
