So the new pro billet dist didn't do the trick either. Installed it just like the instructions say. Same as it was. Started reading some info on the net about one thing and another. Called Holley and their tech said it sounds like RFI issues. Says two ways to go, run without timing control or buy their Dual Sync distributor because the Hall effect design isn't affected by EMI/RFI . I have a hard time believing something I can't see or touch so I figure he's just blowing smoke up my skirt to get me to spend the bucks for their dist. Read one article where the guy was having similar issues and he removed the alt belt and thing changed drastically. I figure WTH? Don't cost nothing. So I drop the belt off the alt and miracle of miracles the car starts and actually runs pretty well. Belt on, no run. Belt off, runs. WTF??? Ok so now I'm starting to believe there may be something to this " electronic noise" they keep talking about. So as of right now the pro billet is gong back, the car is going back to no timing control and I'm saving up another $150 to pay their blood money for the Holley distributor to manage these made up gremlins. I'm really hating electrical stuff right about now.
