The things that continually surprises me on camshafts are:

1) How much more important duration is than lift on the cam. Getting the duration right, for the CID and headflow, is way more important then squeezing every .001" of lift out of the cam.

2) How much more important duration is than the lobe profile itself. Even when we talk about "Best lobe profiles"... If the motor combo wants a 260@.050" duration cam, worrying about which lobe profile you're going to use at 250@.050" won't do you any good at all!
