What are some inexpensive mods that I can do to my Car. I want to start getting into shows, if that is feasable. At this point, I really don't want to go with the Chrome, as of now.

I am considering changing all the spark plugs and wires. All the tubing, either buying new ones, or taking them off and painting them. Also, painting the raised letters on the shield is another thing. K&N CIA is a possibity. Also, I will be getting more decals.

Here is a pic of the engine. Any idea's?
