Would buying a new upgraded valve body be worth it for an old engine of will it be a can of worms? I remember reading a pretty in depth article for the 80 about 5 years ago in a Peterson 4wd magazine, iirc, about one company that made these for more hp more torque engines, and have been looking into it. Will these put the pep and torque back in my vehicle. Any insight is appreciated. Experience is usually worth more than gold.

) the shift timing maybe controlled by the ECU, if so, none of the kits will have an effect on it. Lucky the rig is equipped with a shifter, allowing the operator to select whatever gear is felt to be appropriate for the conditions.
