1. Rocker arms with a roller tip and a increase in lift
2. Edelbrock makes a cool maniford and performance throotle body and cylinder head package for the 4.3, also putting an electric waterpump will give a few more horses. Large valves also. Theres also some good ignition systems coming out and K & N filters makes stuff for your 4.3, I like my 4.3 in my 2000 S10 its kicking ass here in Germany on the Autobahn:) Maybe i soup her up soon also!As for MPH I didnt really think about that, your engine as it came from GM is the best its going to be for MPG really, keep your AC off and if its a truck the tailgate down for less drag, also the right air in your tires and light loads in your car or truck help fuel economy, as does regular servicing.
