Magnum 380HP Camshaft

ok...since I have two of these dam camshafts..i yanked the 1st one...and put the second one...also got a BIGGER degree wheel....she said size matters...

With the second 380 hp cam...I get 230 at .050....but as with the 1st one I am getting .305 lift at the cam...times 1.6 gives me .488 lift......suppose to be .501...
cam is center lined at 106

are the rockers REALLY 1.6? Are they oem, or aftermarket? Have you tried measuring at the valve retainer, to determine actual lift? Maybe that might calc closet to .501".
