Advancing the cam makes it build more low-end torque, while retarding the cam makes it build more high-end horsepower. Performance cams are designed to run 'straight up'. If there were an advantage to advance/retard it would have been incorporated into the grind from the outset. Usually, people advance or retard a cam to make an unsuitable cam more suitable for the application.
From a side-by-side comparison, the Lloydz cams definitely have a (not sure the term that's used) wider profile, so they'd open sooner AND close later (granted I dunno if that was the intake or exhaust lobe I was looking at).. Even for a mild cam upgrade it was noticeable from a low-rez pic.
I'll be interested to see what Kyle has in store with his recommended mod he quoted me (VM1-DR cams, timing wheel, Lloydz filter). Very curious how we'll end up with the timing. I imagine he's got the combination memorized from experience.
