I've got a 71 high performance 350 in my 84 firebird and was wonderinng what I could do to get a great increase in my performance without spending too much cash (too much is thousands and thousands, hundreds are fine)

Cam, intake, carb, and headers.... the most basic, but will really liven up the engine.
