I vote KA. I know its not gonna be different because its becoming more of a "average swap" these days but people do it for a reason. if you wanna auto cross or hill climb the KA has the torque. if you want to be different then boost it. 10 pounds on a KA would be crazy on power, weight isn't bad, and cost is uber cheap. but all in all, do what you wanna do. its your truck so if you like it that's all that matters! either way the truck is way bitchin :thumbup: :rofl:
