I've thought about converting to fuel injection, but I really want to keep it as original and cheap as possible at the moment. Any thoughts?

I had a zephyr with it. 90hp?
The intake and emmissions of the later 70s was insane, 1972 should have a bit more strength if in typical history of its generation.
A very common weber 32/36, progressive electric choke, and get some advice on the displacement for jetting, it is a conservative one.

My late 70s version was so tight it broke its own intake trying to get air. Somebody built something crazy at ford, I hope your 200 doesn't have what mine did. I had realistic motivation and never went through with it, the weber custom jetted, emmissions removed, excpet for canister, fuel venting and return lines, a newer convertor, away it would have went.

200 cubic inch is a giant, and straight sixxes do not want to run, to get a goal of 30mpg is incredible.

keep an eye on those washers holding the exhaust and intake simultaneous going into the block.
