Small Block Cam Info - Magnum Head Swap

on your crane graphs remember to subtract 7 degrees
crane's advertised is at .oo4 wheras the others are at .oo6
I used to use 8 degrees but found on the Camcraft website a listing with both .004 &.006
btw camcraft learned from Harvey Crane not UDHarold
now for MP
MP uses a unique way of measureing duration
but it works out to close to .008 (also Engle and Racer Brown))
so for the MP cams I'd add 8 degrees to the advertised
These additions and subtractions are necessary for dynamic compression calcs too
