I’ve never had a cel. (and yes, it does light up with ignition on so it’s not broken, lol) Currently running the stock AC Delco distributor but also have a MSD 8366 dizzy sitting on the shelf. That one is earmarked for another engine that I can never seem to get around to installing. The 8366 allows you to install different advance springs and stop bushings for custom timing curves, but I don’t know how the ecm would respond to that.


Ok, I'll jot your info down and give it a try after the wedding In 2 weeks, (gotta recoop funds)

I am looking this thread! I have has issues with this. Replaced the distributor wires plugs ecm. Still like to stall. Rebuild the tbi. Without replacing injectors. Ran great for awhile now CEL comes in and if runs like shut. Reset timing after distributor, u plugin the thinking advance if course. I have been wanting to hold out for a complete sniper setup
