Vacuum leak, it was not.

[Nuke427]

I posted a few weeks ago on my car running like crap after swapping intakes. I last posted with an announcement of finding "the vacuum leak". Well, I may have found and fixed one, but it did not cure my part throttle woes. I have checked the vacuum and it is sat. It really feels like ignition. Part throttle under load, missing badly. Idling in the drive, revs free as can be. Full throttle under load, seems to be okay, but probably not as good as it should be, I'm sure the miss is just masked by the noise and acceleration.

I have moved on to looking for an ignition problem. I'm using an MSD Pro Billet distributer and 6AL box. I removed my cap and there was corrosion on the posts. I cleaned that all off and it made no difference. Still crappy. I checked all my connections at the box which is mounted in the passenger side compartment in the cockpit, so no heat stress on it. All connections good. All plug wires seem to be good.

I cannot figure this out, so I ordered a new cap and rotor and all new plug wires. If this does not fix the problem, I'm going to drive it off a cliff.

Anyone had a similiar problem and if so, what was the cure?
I'm getting desperate and willing to buy new everything until problem solved!!!
