Hey new on here, just bought my second mustang. Picked up a 88 gt, has been updated with a 306,gt40 upper gt 40 lower, comp cam 270, bbk headers, bbk throttle body, and I believe original maf. Has 24lb injectors and 255lph fuel pump, this info came from the guy who built it. Couple of questions, pushrod length the engine has a little valve noise I was told the pushrods were a little short cause of heads. Also I need to put a fuel pressure regulator on the car, what would u recommend the pressure to be at? Any help would be great!
