Forget about carburetors and go fuel injection. In my '83 K20 I went from 14.5 to 17+ mpg when I changed to Tuned Port injection. The torque is unreal better. Used to be that pulling trailers at interstate speeds I was on the gas hard at every hill, now it just goes on up. It always starts at the touch of the key. I also have a 700R4 overdrive transmission which would be nice, but a lot more trouble for you to add. I have 3.42 gears. You cannot beat TPI fuel injection for a combination of economy and power-with reliability and simplicity. Uses virtually all stock parts that can be found at any auto parts store in the country.
