You can pretty much max the advance on this engine since there is a ton of PTV clearance.

are you talking about 3-5k rpm? or how much to advance and retard the cams?

Thats not a question I can answer. Due to factory tolerances, some cams may come off the line being advanced 5 degrees, some come off retarded 5 degrees, and some come off perfect. Since the camcom works in percentages, its not a easy thing to guess at, if your engine was like mine where the cam was retarded 5 degrees maxing the advance worked, if its like my old engine it would likely cost power.

I was at max advance between 3-4.5 and tapered down to 5.5 with everything above that retarded slightly. This is something that really needs to be done on a dyno.
