Scott:
Quadrajets are good, but pretty long in the tooth these days and refurbishing costs a bit.  Plus you need to be able to tune it.

I threw an edelbrock onto the ZD and bought a metering rod and jet kit for it to tune it a little.  Runs great. Starts all the time, even without the choke hooked up. Can't fault it.

I bought a reconditioned one from Burwood Carburettor Services back in 2000. I haven't touched it since and it hasn't missed a beat.

the quadrajet is a good old very old design way out of any patent considerations
and there are copies with some variations on the market by well know companies.

I've often wondered if bolt on fuel injection systems might help to improve fuel economy in a case like this. I recall that Motor Trend/Road Kill have used them a few times and them seem pretty slick. As a bolt on they could always be reversed if the car is sold and the new owner wanted original.

I don't have any experience with these but it's an option.
