looking for more power

Ok here is what I have installed so far1.) powergrammer2.) throttle body spacer3.) k&n filter4.) flowmaster 70 series mufflerok Iam looking for more power without tearing into engine interials. i don't have the income to afford a supercharger at the moment. Any suggestions? Is a air intake worth the 200 bucks they want for it? Are headers worth looking at. I have heard both pro and con on these two items. I am also looking for things that can be done in a weekend becasue my fullsize is my daily driver.

I would get some headers and you might look into bigger spark plugs wires and maybe an MSD ignition. An electric fan will also help out. Sounds like your off to a good start.

anybody else

air intake with the headers will improve it a lot also you mite can get a bigger throttel body size
