I bought it from Dave Weber(ModernMuscle) a while ago, it's what he recommended. Supposed to be good to 600hp. The return line is plumbed right from the regulator, only requires a single feed line to the motor. I can't remember what it's preset at....dont have the paperwork in front of me.
I'm going to give it a "go" and will adjust accordingly when it's time to fire. The motor will probably get a cam/headwork anyway, so it wont be stock
