I removed the throttle body and intake and picked up an Edelbrock 2104 on Ebay. I plan to reuse the HEI distributor and Quadrajet as they both had recent rebuilds prior to the engine failing.
My questions are related to fuel delivery:

1. How much fuel pressure does the engine need?
2. What type of electric fuel pump/pressure regulator is the best for this application?

Thank you in advance for your help!
I can answer this much for you, If you are going to be running a carburator you only need 5 psi for the fuel pressure.
