Default Recommended Fuel Pressure
I have a 1996 LT1, 401 cubic in with 12.5 compression. Have 42lb Lucas injectors and walbro 255/hr fuel pump with aermotive adjustable fuel pressure regulator. Was wondering what is the recommended fuel psi i should adjust it to.

The OEM fuel pressure is 43.5. This is also most likely the same pressure your injectors are rated at. I would start there.
