95 LT1 383 GM hotcam FPR required?
I need to replace the fuel pressure regulator on the fuel rail. The engine has been bored and stroked and is cammed with a GM hot cam. I also stepped up the injectors to 32lbs. What fuel pressure will I need? Will the standard OEM FPR do the job? Or do I need an adjustable FPR?

Factory pressure is fine, base pressure should be 43psi with vacuum line removed.
No need to get an adjustable.
You should correct the tune if necessary, not the fuel pressure.

After studying how the fuel injection system really works, all I need is 43.5psi on the rail and a good fuel pump. It will also need a PCM update to control the injectors and ignition and other things needed for my engine swap. Thanks for the reply.
