I need an old guy....
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.

Haven't done compression check yet since rebuild. Was waiting for rings to seat well. close to 800 miles on it now.
The catch is, it was doing the same exact things BEFORE I rebuilt it. Thus why I started rebuilding it. Eliminating possibles.
It has been rebuilt in stages. Fixing a few things at a time. This last time I had it out I had it bored out and I installed new pistons and moly rings. The old ones were worn out.
I've been working on this for a year already.

Did you by any chance put a 4bbl intake on two bbl heads, the intake ports are huge, and the head ports are a lot smaller, #7 may not be sealing like it should, sucking air there instead of through the intake.

Nope, but that is a good question. It has a stock 2V intake on 2v heads. I've wanted to buy a edelbrock intake so I can get a 4 barrel carb on it.
I've tried The vacuum leak possibility, had the intake off a couple of times and made sure it sealed going back on.

Yea as far as I can tell. I don't have any electrical problems anywhere on the truck.
One thing that has kinda concerned me is that the #7 plug wire won't zap me, but it still throws a spark through the plug. weak compared to the others though. Maybe not strong enough to light the fuel charge. I've switched plugs and wires around. Didn't make a difference.
I've checked the cap and rotor, all looks fine and the cap is in the right position.
