Beings I work in the Parts Department of a Ford dealer I am a tad partial to Motorcraft stuff also. The FRPP ones are cylinder marked. But I agree, the Motorcraft ones would work fine.

I have found motorcraft to work great on some aplications and not to well on others. In my 460 motorcraft never would hold up. I had to use Bosch plugs and wires but on my 390 it ran the best with motorcraft parts

I bought one of those inline spark testers and all 8 wires light it up.
There's just too many things that don't make sense anymore.

To me it makes the most since that it's ignition. If it was fuel there would be more cylinders with problems.
I had this engine completely apart and torn down. Anything that wasn't replaced was inspected and OK'd to run. (The crank and rods at this point) so to me it's almost impossible that it's a mechanical problem.
To clarify once and for all, my Pushrod problems were do to faulty lifters. I have had the engine apart since then, and the cam lobes are perfectly fine, and there is no valve damage at all.

Ok. Here it comes.... I need help.
I don't know what's wrong anymore. My engine is still Misfiring. Cylinder 7 is still the trouble maker. And a couple others might be weak. I've done everything I know how to do to diagnose and fix it.
So if any of you guys in the greater Phoenix area (south east valley would be great!) would be willing to help me out in getting my engine tuned up and running right, or know a shop or guy that knows the older engines I'm all ears. And if I could find someone that knows the 351C specially, well, that would be all too lucky.

Same heads and intake, but this is a entirely different engine that I rebuilt. The original is on a stand in my shed.
In short, the story goes, engine one ran great. Truck got replaced, so it got parked for the next 20 years. I take possession of truck. Engine one is misfiring and won't pass emissions anymore. Replace the basics on engine one, still don't run right. Engine comes out for rebuild. Meanwhile while browsing Craigslist, I run across engine 2 for a good deal and decide to buy and use it. Engine 2 gets minor overhaul but with all new valve train components and a hot cam. Still doesn't run right. Replace hot cam with stocker. Still don't run right. Distributor advance mechanism fails, replace stock with new HEI. (The HEI made a big improvement by itself, but still don't run right.) Engine gets pulled and heads taken off again. All is well except #7 rings are lined up. Re set rings and goes back together. Still don't run right. Decision is made to bore and install new pistons and rings. Current state.

If you really want to rule out ignition, take it to someone with an oscilloscope. By scoping it you can tell the health of every cylinder's spark definitively. No more looking at spark color or shocking you, get the actual numbers for your Firing KV and burn time. I find with tough problems it's best to get all the hard numbers and try not to jump to conclusions. Hope you get it sorted out!
