Do you have an electrical choke or a manual (mechanical) choke? I was debating if I should use the wire that goes to the Rochester QJet or put in a manual choke. I believe the 750 chokes have two wire connectors, a power and the other probably ground.
I was also planing on a fuel shutoff solenoid valve 12VDC and was wondering about a good durable one if anyone had used them. Would be a good way to block fuel flow when not in use.

IMHO, although the aluminum pumps look really cool, they don't perform any better than ferrous pumps for street applications. I've been happy with the Milodon high-flow iron pump on my SBC. In reality, as long as the radiator has unobstructed air and coolant flows, even a factory pump should circulate the coolant just fine.

Thanks bd, that is well written and it did not occur to me to look at the technical info on the forum for that information. You did very well and I appreciate your assistance and will use what I read. Unfortunately, I already bought a water Edelbrock Water pump. What brands do you recommend?

You're probably suffering from the same thing on my '89. I can hear it run when I apply B+, but it sounds like it's sloshing gas when I listen at the fill pipe.
The rubber hose section on the pump assembly is rotted out and the pump only produces 5 lbs of pressure, as the rest recycles back into the tank.

I don't recommend the Edelbrock aluminum water pumps. They are a great idea but have a propensity to leak past the shaft seal with a few hours of use. Have you looked through How to Seal Threaded Connections and Fasteners?

Does the torque values change when bolting down aluminum parts like heads, water pump, and other parts from the suggestions in maintenance manuals?
I used to use RTV on bolts going into water jacket holes, such as the water pump and some head bolts, that may not have been the best practice. What is the best sealant to use, gasket sealer or something else?

I agree, it does look like it would be a carrier bearing mount. If you're never going back to a 2 piece drive shaft, just cut the entire mount out.

Looks like a bracket for a bearing on a two piece driveshaft. If so grind the rivets off and pull the bracket

I have a stock fuel pump without a return on a 383 stroker with a 750 holley vacuum secondary. Pump was putting out about 9lbs. Had to put a pressure regulator on it to bring down to 6lbs. Everything works fine.
