Owners of P30 454 chassis, what are u setting the timing at?

Vacuum to distributor is straight from the manifold.



No emissions gadgets that I can see. Worry about engine knock if I crank it up 16 degrees advance with regular gas. Might meet at the middle at 10 though. It's not the easiest thing to set the timing on these as you have to crawl under it to check it, then go back inside to adjust it.
