Engine Dieseling - Options?

247/254 @ .050 - 108 lobe separation, 508 lift intake/exhaust - cam had 4 degrees built in, I installed retarded it so it would have 2 degrees, changed the ICL from 104 per the cam card to 106 per the mgi speedware website - cam was degreed in - will see how it does next weekend, if the valves don't rattle I will be OK for now
