Has anyone done and major mods to the 4.2? I'm put a cummins in it in 4 years but if I could get some increased power now for less than 1000 bucks id like to do it. I already put a weber carb on it. Changes to ignition? Headers? Bigger fuel pump maybe? If you guys have done it let me know if it adds that much
