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

Ok, without doing a bunch of that is way too much cranking compression for that cam timing and CR.

Did you degree the cam, or line up the dots.

If you did the former, I have no idea what’s going on.

If you did the latter, you have no idea where that cam is installed.

Just trying to get my mind around why the cranking compression is so high.
