In a previous post on this thread I mentioned that you will rarely find a cam off spec more tham 3-4 degrees and if you do, I suggested dumping the cam rather than trying to correct it. To clarify, I have degreed in lots of cams over the years ( remember, I'm pretty old ), but I can't specifically remember degreeing in a Mopar cam ( probably did a few along the way )so I can't comment on their quality. When I have run accross one that was out more than 3-4 degrees, that discrepency often existed from lobe to lobe ( on both the advance and retard side ). Something you can't correct - hence - dump the cam. IMO, there are a lot better grinds out there these days than what Mopar has to offer( more area under the curve without sacrificing driveability ). I'm running one ( flat tappet hydraulic )right now with well over .600" lift that still pulls 10 - 12" vacuum at idle.
