I actually had Chad at my house and couldn't get logged on from the main pages. But if I reply to a post and then log in I don't have any problems

I think I'm getting away with 20 degs because I have an iced down water to air intercooler and I'm running a Snow Performance water/meth system. I tried less total but the power was dropping off. See ya in '12

Yeah, there are several variables. The modern chambers for big bore engines have small high swirl designs.

Bill Fowler's big ford only wanted 24-26 degrees of advance at WOT. Chamber efficiency apparently is the cause of this.

It's probably related to why you can run so much advance at part throttle, when there's much less charge pressure in the chamber.
And the thing about smaller engines...a smaller bore (and smaller chamber) means there's less distance for the flame front to travel across, so it takes less time, so you need less adavance.
