360 Idle Quality

It can get confusing. Here's what no one has spelled out for you. When speaking of advancing or retarding a camshaft, Lets say "we're gonna advance the cam 6 degrees". What that means is, we're advancing the CAMSHAFT six degrees at the CRANK. Camshaft degrees, even though we're moving the camshaft, are spoken about in crank degrees. 6 degrees at the crank = 3 degrees at the cam, since the cam turns half crank speed. But, everyone speaks in crank degrees, since that's how an engine's timing is read. Make sense?
Got it, thank you.

So does it seem surprising that I can run 48 degrees of total timing and have no detonation issues? Does low dynamic compression and aluminum heads allow for that much advance?
