Most custom comps I see DON'T have any advance ground into, but you will be losing some lowend trq and maybe alittle upper rpm power, but with that 112ICL(if ground with 0 advance), this cam will carry peak hp past 6000k now.

Isn't it true that you'd need an adjustable timing gear to add any advance during the install? If you use the stock timing gears, wouldn't moving it a tooth from dot to dot be too much?

My understanding is that degreeing the cam just allows you to verify it was truly ground to specs, but you'd need an adjustable timing gear to adjust the advance.

Either do it way an adjustable t/c set or offset bushing on the cams dowel pin.

Ahh, cool, I didn't know you could effectively move the dowel pin like that. Makes sense.

Advancing or retarding a cam by crank position is just plain dumb.
