How many miles are on it?

What kind of plugs did you use? What did you gap them at?

What does your temperature gauge say when the engine is warmed up?

Does it run okay? Any spitting, sputtering, or stalling?

Can you smell gas?

Unrelated:

If you haven't done so yet you are do for some fresh anitfreeze, too. You also need to replace your radiator cap with a Stant from Advance Auto (stant is the best, but anyone other than AC DELCO will work). The AC DELCO cap that came on these trucks are defective and will cause you lots of problems if not changed out.
