Distributor
Don't think that an MSD is the answer either, I had an E Core MSD and put it in my small block for nearly a year and everytime I let the car sit for a few weeks I could not start it. It appears that it needs high battery voltage to fire!. Well it finally failed about twelve months in so I put my chinese junk $60 unit in and it, started much better and ran better as well. I eventually put ICE ignition system in it but I purchased a 318 car that had sit for 30 years and recoed everything and put that junk distributor in it and it runs real good!
