lt1 fuel pressure setting?
Im trying to set my fuel pressure and have done some research, from what I have read it seems like 39-41 seems to be the best for the lt1 but mine has 120,000 miles and wasn't sure if this is too lean for a car with high mileage.
Also if i want so set my fuel pressure between 39-41 should it with the vac. line on, vac. line on, or the vac. line off and plugged?

Follow the specs in your FSM. I believe the pressure is to be set with the vacuum line disconnected, but follow the book. A couple of pounds of fuel pressure, one way or the other, won't make much difference in the A/F ratio most of the time, because the computer works through closed loop to keep it at stoichiometric.
