Did california fall off into the ocean, and "tomorrow" never came?
did you drive it?
Yep I swapped out the Accell shorty header plugs for some regular AC Delco plugs. I also put on new ceramic covered boot wires that are supposed to handle the heat of the headers but just to be sure I also wrapped them in heat insulting material.
I checked and double checked the firing order and made sure all was good with that. I checked to see if the timing chain is loose (via my timing light) and it seems fine
Then took the car out for a drive and it still pops badly through the carb and now it's even popping though the exhaust as you let off of it, but that may be the side pipes with not enough back pressure.
I took the car out and did some tests by running it up to 5000 RPM and it seemed ok once I got past the popping and stumbling but started missing about 5200 PRM. That just might be valve float or where the Pertonix quits??
