Fuel pressure at high altitude
87 GTA 350. I live at 4500ft and I got an ajustable fuel pressure regulator. The engine seemed to run best at about 36psi.
Does this seem right. Anybody else at high elavation.

I used to live in Alamogordo NM (4200 ft) and mine ran best at 43 psi. I remember reading somewhere that at high altitudes you won't need as much timing and fuel pressure. You'll just really have to experiment and give the engine what it wants.
