Phasing out that ESC is the way to go, It could render your truck completely useless one day if it decides to act up. If your engine pings you just adjust your distributor back a little bit.
Chasing a firing issue is a pain in the ass for me. I start with checking everything one part at a time, I got stumped a while ago when my truck would start and run fine and then randomly have no spark at all when I tried to start it later. Turns out I dropped that little ground clip that went on the coil while doing my tune up.

Hey irishman999, yeah from what I can tell it's stock HEI and it does have the coil in the cap.
I'll definitely look into disabling the ESC - even if it's not THIS problem, I don't want it acting up in the future. I did a bit more research and found another forum (lost the link to it, though) where someone explained that the ignition module in these distributors put out spark with max advance and then the ESC retards it to where it needs to be. So I guess that's how it does electronic spark advance. Makes sense, but I don't know of any way to test it.
Seems like I need to probably switch over to a more standard HEI setup when I can find some cash to do it.
Thanks again!
