E85 conversion!

Sprayed alky today. About 3 on the dial. Turned it back off after it started breaking up again.
Still have a breaking up issue tho. At a loss as to what to do.
 
I would start with plug gap. should be .028ish, maybe a bit tighter.
Then try changing AFR / timing.
Then go after ignition and valve springs. Toss up as to which could go first there.
 
I was at .030 and regapped them to .025. I'll see if that helps. These are NGK B8EFS
The breaking up happened with the AR474's when I first made the switch to E85.
I tried Really lean and really rich with no avail.
Timing was 18° at first and I gradually ramped it up to 27° and back down to 25° where Im at now.
Bought HO coil pack and ohmed coil and wires.
 
Fixed it. Tightened new plugs to .020-.022 gap and spark blow out is gone.
I have been spraying alky on top of the E85 and it pulls harder. It not only pulls harder, I can make multiple pulls without loosing any power and its 85° out.
Cant believe how hard it pulls now. Front end stays up all the way to top of third!
 
Look for Camper Daves set up We will park by him
