I think that following the cam manufacturers recommendations would be a good idea. Okay, now that the weekend is coming, they surely won't answer the phone. The local auto parts store has a few decent choices. I use Valvoline VR Max. It has higher zinc than standard oils and costs about $ 4.00 per QT. Z Alt has been advertised in the Mopar mags. I also use the Comp Cams break in lube during cam break in and at every oil change as cheap insurance. I dont drive my hot rods but 1500 miles per year, unlike my 40,000 mile per year '07 Ram truck.
