I swapped in a stock points dist and it ran like stock. Travis.. 70 GTX project, orig 440-4, 4 spd, track pack, FC7, stripper/street racer special.

I'm guessing you followed the directions give. Did you check the ballast yet? I had the same issue a few months ago. car would start up and run above 1500rpm as soon..and I mean as soon as I dropped the rpm it would shut off. Acted like it was running out of gas. I swapped ECM, Votage reg, cleaned the carbs. Long story short, the ballast went bad. Over to the shelf, new ballast and 2 minutes later problem solved.

(go get a holley) This is where I will agree wit hyou , the performer 750 is a piece of junk , but it's not the main reason behind his idle problem. I thought with that CCJ ready to run you have to ditch the ballast resistor ?

What ignition box are you running? If ProComp.... Chuck it in the trash, their distributor is OK (cloned after MSD) but the box is cheaply designed and not reliable. We just pulled one out of a friend's 65 Sat and put in an MSD starts/runs fine now.. Just my $0.02..
