Second your question above , no wrong , too much advance down low will hurt low end torque , timing is a mystical thing , if you are running vortec styled heads , heart shaped combustion chambers , they like less advance , 32 degrees total

without a load the engine will rev faster with alot of advance down low , an engine with a load on it , especial a pushing a heavy truck , in other words you truck in drive will run like poop

lol I've been wanting a big cam since I was about 12 years old, I couldnt resist no vortex heads, I picked up a set of Pro Toplines but I don't remember a heart shaped chamber. I'm gonna toy with it today as soon as I figure out a dang lower radiator hose that will fit. Tranny cooler hard lines are in the way and the hose it had was bending over the frame...
