Be sure not to damage the float & sending unit for fuel guage, if you are reusing stock instruments. If using aftermarket guages, now is the time to replace sender or make sure stock sender works w/ your new gauge. Mine does not read accurately, I have a 0-90 ohm aftermarket guage & stock sender, it reads 5/8 full when tank is full. 10-180 ohm guage might work better, still working on it.
^^^ This. Either electric fuel pump or mechanical. Mechanical should bolt right up to your block and would not require any goofy wiring. Or you could use one of these: Buy Holley 12-801-1 Electric Fuel Pump 12-801-1 at Advance Auto Parts
Looks like it's for a 305, but should work for you. But, if that's not enough flow, there's "Edelbrock Quiet-Flo" electric pump that'll put out up to 160 gph for you. If you go with an in-line electric pump, mount the pump close to the gas tank with an in-line filter between the pump and the tank. I'd also put another filter up by the carb. You could probably use the factory wiring for it, but don't quote me on that one...you'd need to check the specifications on the pump and the factory wiring (amperage, loads, voltages, etc...). Disclaimer: I'm assuming a lot about your set-up, but this is what I'm thinkin
you could do. As with any info on the internet, take it with a grain of salt, and do your own research. OR
as UnlimitedLJ said - convert it to fuel injection - just google "tbi conversion".
