I was coming home today with my four dogs and 40 pieces of sod in the bed of my 62, 3/4 ton, long bed, stepside. I was going up a slight grade and could barely keep this truck going 55mph. I began to give it more gas when I realized that IT WAS FLOORED. Either this 235 is a total dog or I have it mistuned. It was rebuilt about 4000 miles ago and has the original 1bbl carb. How can I get more power out of this thing?
