i have a caprice, first of all, so i dont care about going fast. i just want it to sound cool. i dont like cars that run smooth. i want it to sound like its barely running. i was told that if i change the cam it will give me the sputtering uneven running im looking for. would the cam be the only factor affecting how it runs like that, or would i have to go all out with performance crap and actually have to spend lots of money?
