LT1 Fuel Pressure
LT1 Fuel Pressure
I took my fuel pressure with a gauge. It is 39 PSI after pressurizing, 40 PSI at Idle, and between 40 and 47 or so when the throttle is applied. There is no bleed off when I shut the engine off.
Is anything wrong or is this about normal?
Thx in advance for your replies.

Is this not important?

Tape the guage to the windshield and run the p*** out of it and the pressure shouldn't fall lower than idle with the vacuum line off.(41-47)
That is the checking procedure.
