Engine Cutting Out! What to check?

Ok that unit does provide multiple spark discharge but nowhere near what an MSD ignition box puts out. If I may ask, what is your reason for using the pertronix brand? I put a pertronix conversion in my dads boat, and although it is much better than points it's nowhere near what you need for your application. If it were me I would go with a MSD pro billet distributor and an MSD 6AL box. It's what I'm using in my D1 pro charged Dart and it works sweet and its reliable. Especially with you running 15 to 1 compression you can't afford to have any detonation issues. You will scatter that motor extremely fast. You can also open up the plug gap with the box which will allow a better hotter spark. Also to be on the safe side check to make sure there is no debris in the supply line screen ( if there is one ) because that hot fuel is rough on rubber fuel hose especially if its old line. Good luck man. Like to hear what that 15-1 motor sounds like. Bet it's nasty. Post a video.

I talked to an engine builder today and he was saying that the pertronix ignitions like the one I bought are "badass" in his words. He said he uses msd units in his cars but he beats them up a lot and the pertronix would work good for my motor. He highly recommended them. The lines should not be corroded at all. They are only a couple months old. The entire fuel system is. These plugs are NGK5 and I agree they are too hot of a plug that's all I could get a hold of at the time. One shop said I could run champion GR9's or something like that around town. At the track will probably run NGK8's. For a video, go to my build page in my sig on the last page.
