Advancing Camshafts: Physical vs. Built-in When buying a cam with advance built in, you slid it in dot to dot and run it. However, if you're wanting to add more advance to a camshaft, you must physically advance inside the motor.
Just curious if there is any difference in either. Advancing the cam physically inside the motor changes valvetrain geometry, but still serves the same purpose in bring the ICL down. I am running a 114 LSA cam with zero advance right now. Mid-range sucks, even with 4:10's so I am thinking about a adj. chain and bringing it down 2 degrees to start. Putting it on a 112 ICL opposed to the current 114 ICL. Then possibly working my way down to a 110 ICL.
Thoughts?

I think so too. I originally got the zero advance to help increase P2V clearance, and reduce some cranking compression but this cam needs to be backed up at least 2 degrees. Above 3500 rpm's it haul *** but puttin around town it has no ***** at all..
I am just curious about physically advancing the cam in the motor, as opposed to have a cam with the advance already built in. Is there any real difference?
