MSD nightmare
have a 8360 distributer and added the 6al box. it ran on so i put the diode onto the alternator. still runs on and when the key is off it runs cleaner/better. the local guru says i have to change the module in the distributer but the msd instructions say the 8360 still triggers the msd. so i switched back to the stock configuraton off the box and now it runs like ****. its definately dropping cylinders. very frustrating. furthermore, with the key off there is voltage to the ignition hot. not enough to keep the stock system running on though i believe this is the culprit to the msd run on. where do i start. one more thing. the plug wires were 2-3 yrs old. could the few minutes of msd box been enough to fry them if they were weak, hense the new miss even without the box?

Try for service from Jacob/holley. It sucks, not like the service Jacob's use to give before they were bought out.

MSD has a good trouble shooting guide in their installation section on thier web site..I run a MSD 6AL..once,my faulty ignition switch affected the box...don't junk a good system..also,it is recommended you run thier spark plug wires..

make sure your not running a platinum plug, msd doesnt recommend it. They do recommend using their wires as another poster said, stock wires are usually 8mm, MSD makes 8.5 mm. They even make a custom length set for the small block vettes, however one of the shorter wires was about 3 inches too short, so much for a custom set. I had to call MSD and they were more than happy to cut me a wire to my needed size.

I'm also running their complete 6AL ignition system. Ran right fron day one. Didn't even need the diode. You might try giving their tech line a call and see if they can help you out.
