Well it really depends, If the trucks that old im sure the engine really has a lot of miles on it. Tossing a supercharger into it is just a waste of money. What kind of engine and what kind of miles are we talking. You can get AIRRAID air intakes, Edelbrock shorty headers, Flowmaster exhaust, MSD distributors, Performence a lot of parts it really depends. As far as a engine swap 350, 383 and a 454 if it would fit.
