... cam choice for 360? I need advice.

when they regrind a cam, they basically grind away material to make it have a lower "floor" so the cam has a higher lift as seen from the rockers. If you look at a Mopar cam, the lobes barely fit into the bearing journals so they cant add anything, so they drop the floor, get it? And a regrind has to use the basic shape of the stock core it uses, as they cant really manipulate the lobe seperation (you cant grind that) al you can do is raise the lift potential and maybe add few degrees of duration as the lobe is now "thinner" than it was so they is added duration. Roller cams are expensive, but you can get away with using the same roller lifters. With a tappet lifter cam, you always need to purchase new lifters with a new cam as it "laps them in" during cam break-in. Rare cases can a lifter be reground, mainly solids. VW amd mushroom lifters come to mind. Check Oregoncamshaft.com. I got a quote recently for $75 for a regrind for a slanty, and they had a few different flavors too.
