Ok....This is for all you ignition geneius' out there: I have a rebuilt 350c (100k miles) i w/MSD offroad, Accel dist., Edelbrock carb. I installed the MSD ~ 10 months ago and ran great till bout 2 months ago. Problem: After running the truck for a while, engine dies and will restart after ~10 min. I can run the truck for a day, then the same issue occurs. After consulting with MSD and even sending the box back to Texas, they tested it and it was fine. I rewired all hookups. Replaced: CAP, ROTOR, PLUGS, WIRED, COIL (all MSD), and problem still exist. I thought it was 'secondary' high voltage cross talk, but ????. I did notice that the timing 'creeps' upward from ~6deg to 10-12 deg at idle. When the truck dies then starts up again, the motor cranks slowly as though the timing is very advanced. Is 'cam walk' a issue here?? Im ready to replace the Accel dist. with MSD HEI pro billet..... Does anyone have any other ideas?? ... frustrated BUT not giving up!!! HE will always get you out of the mire clay!!!
