Re: carburation system
Yes, throw away the carburetor and add fuel injection. Mileage and power should increase. Either Throttle-Body style or Tuned Port style are relatively easy to swap to and are tried and true systems.

Re: carburation system
Let me ring in here and ask what would the mileage bump up too with both of the fuel injection systems with his engine but with out the 305 heads and going back to some stock 350 heads. mjgord51

Re: carburation system
The only apples to apples compare I can give is my own. I have an '83 K20. I got it with 42k miles. It has a 700R4 and 3.42 gears. It always got 14ish in town and 17ish on the road. At about 150k a cam lobe went down. I pulled the engine complete and went to a '90 Corvette Tuned Port 350. Now my mileage is 17+ and town and over 20 on the road. Towing/loaded is noticeably better; with the Q-jet you were always on the gas at the slightest hill. Now just a slight touch and it pulls. That swap is nothing changed-stock manifolds, same transmission and gears. So 3 mpg better which is better than a 20% improvement. That is my experience, yours may vary.
