LOL I saw Damon's post when I came over here and started laughing. Someone looking for the same info I am. hehe
Alright, for those of you able to dial in your spark advance, what kind of advance do you have? I dont mean full advance only, Im looking for points along the curve. Say Y rpms @ X amount of boost @ Z A/F ratio
Just looking for some comparisions to my program.

Guido a 406 running 30# of boost here only runs 22* of total timing during the run. It makes over 1800HP. Air/Water Intercooled too.
The 383 im putting together with 6 PSI is goina run about 30* total, roots.
the 355 My friends got runs 36* total under 10 PSI, but its intercooled.
The first motor, the 406, melted 2 pistons because he had his timing locked out at 28* to set the cam sensor and did not set it back to computer controlled. it only took 28* to melt those pistons down. I still have one of them.
