SO I've been thinking of regearing my 65 230 4spd C10 to higher gears for better highway driveability. The question is how high can you go before you lose much power? I prefer to keep the stock 4spd 230 setup; maybe just regear or swap out the rear. I see you guys recommending a 3.38 gearset. How does this all work out as far as power and going up hills and such? Thanks....
