Hi guys. I recently put a 331 stroker in my 89GT. It has a 75mm. mass air flow, 70mm. throttle body, holley systemax intake, AFR 185 heads, 30# injectors, cold air intake, off road h-pipe, and 3:73 gears. I'm about to put a walbro 255lpf fuel pump and an adjustable fuel pressure regulator. I'm just wondering what I should set the regulator at. I'm going to get it tuned, but I want to break the engine in first. Any thoughts on what pressure I should set the regulator would be very helpful. Thanks
