MSD E-Curve

blaster SS E-Core,

Might be what's causing it then. It would kick back through the manifold and sputter on you but wouldn't with an oil filled one? Like so

Yep. Sputtered just like that. Totally fustrated because I was going through this on a brand new motor trying to break in the cam and not was down the cylinder walls with fuel.

I sent it back to Summit and the second one did the same thing. :banghead:

Went to SEMA at was ready to go postal if I had to. The MSD guy at SEMA admitted the SS E-core had/has capability problems with the E-curves. The earliest E-curves did not have this issue. That is why the AREngineering (AndyF) article in Mopar Muscle shows a SS E-core coil with a E-curve distributor.

Crazy thing is, I actually tested my E-curve on the old motor in my car. And it worked fine. That's what fustrated us so much. BUT when I looked back at the pictures of that trial run install...sure enough we had the old oil filled coil in there. :banghead:

To test this, just put on any old oil filled coil that you know works. That was what the MSD guy at SEMA told me and sure enough it worked. I've run the E-curve since last December. Rock solid timing.

90% sure switching to an oil filled coil will fix your problem.
