Depends on how much money you got to spend and what your goals are. Probably will need headers and an intake and a dyno tune to get much done. HEI ignition coils and fancy wires doesn't do squat. I custom built my own wires because I needed the length and got a decent deal on wires and the crimpers.

Time to fill in your profile.

Automatic or stick?

Automatic = stall converter and gears
manual = gears

MORE $$$$$

Cam (will need custom tune so start looking for someone in your area that can do this)
Heads
Intake
Headers & exhaust

Driver training....

Long tube headers is the best bang for buck, look for HTC coated headers which will keep the engine bay and floor cool.
I got headman HTC coated headers and they are great, quite cheap too.

TPI engines love headers, will knock almost one second of a quarter mile time.

For headers, get a set with 2 priorities in mind. First, how easy it is to work around. Secondly, how easy it is to install.
