Small carbs

Anyone know much about the old Rochester Monojet carbs? I just acquired a Chevy k20 with an 8 ft service bed full of old tools and a 292 engine. I got it super cheap because the rear main is leaking, the gas tank is leaking and it has some rust, I was planning on using it to haul firewood and scrap metal from work, but the thing just has insane torque and ok economy. Starting with the tank bone dry I put one gallon in and drove it home, 37 miles total, I made it 14.8 before I ran out, 13.2 the next gallon, in 30 degree weather with what im guessing is 2500 pounds of tools, snow plow rigging on the front, and the massive tool bed. Im curious to see what it would pull without all the weight. Anyway, are ther any tricks to tuning these old carbs to get better mileage other than just turning the mixture screw? Everything I have read says chuck em and get a four barrel but the intake required to do that is almost $400, and thats alot of gas.
