To much cam??

Exactly, Rob-that's where I was driving. He installed it straight up, so advancing it would likely help out. What I've seen is timing sets (what kind, did he use?) that actually retard timing a few degrees-as much as 6* with stock type timing sets or low budget double rollers.

I'm actually kinda waiting for younggun to come on here and say we're all overreatcing. :) since he's running a COMP 294S Magnum grind in his 383 with 84cc Edelbrock heads. But I think he's running more stall and more gear...pretty sure those Eddy heads are about a good 6cc smaller than the 906s too.
