Q-Jet Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am currently using a stock mechanical fuel pump that feeds my Q-Jet. There is no doubt in my mind that the stock mech fuel pump is delivering way too much fuel. I reek of raw gas every time I exit my truck. I know it's not my cam profile because it's stock. I have a regulator and PSI gauge to install, but I want it adjusted properly. I have the following application:

350 bored .40 over
Stock "882" heads
Flat-top Pistons
Stock Cam
Longtube headers to 2.25" exhaust
Edelbrock Performer Aluminum Intake
Open Element Air Filter

What is the recommended fuel PSI that a Q-Jet should receive?
