Re: degree my cam in?
As I'm sure you know the "curves" for an engine's torque and HP have peaks at certain RPM's. Some of that "curve" is determined by the cam.
Degreeing is just the act of getting the cam dead on the original specs the cam grinder wanted.
Thing's never are perfect, the cam ends up slightly ahead or behind due to tolerances of manufacture.
When all the tolerances end up in the same direction, like all plus in +/-, then the "peaks" curves get changed slightly. The cam lobes can be off slightly, the cam index - slot/peg etc, timing gears and indexes all can be off just a tad.
Generally speaking a 2 degree advance in cam timing will move the peaks down, not less power, but the peaks will occur about 200 RPM lower than specs. A 2 degree retarded cam move them up about 200 RPM.
If you use quality parts, you should be very close, so degreeing really isn't all that necessary for practical purposes.
If in doubt, call any cam manufacturor's hotline.
