Im going to pick up an adjustable fuel pressure regulator and I was curious what a good PSI to set it at is?? :dunno:

I was reading an buildup and they did 40 psi on a basically stock motor. They found they could run more timing in hotter temps with fuel pressure at 40. I figured I'd have to play with mine when I get it installed.
