Little advice, search a lil bit to see if your question has been asked before. Here is a very helpful thread:

If you search, there are others.

Here's what I'd do:
- Full tune up (including fuel filter, distributor cap, spark plugs, wires, seafoam)
- Check your timing (Factory setting probably 0* or a couple degrees advanced)
- Check your fuel pressure at idle and while driving, should be at LEAST 12psi (make sure it doesn't drop when you press the pedal)
- After you've done that, you can start with the go fast goodies.

Just as a side note, my dad has the same truck, and it runs like a top, good power and smooth as a babies a$$, with no performance mods whatsoever. I've just made sure it's in tip-top shape for him.
