Ok. So you're after a mismatched combo. A cam that sounds like that will need a looser than stock converter and at least 3.55 gears, along with raised compression, headers and a good intake. If sound is all you want, then just stab a big cam in it and call it a day. It'll be a dead dog without everything else mentioned, but it'll sound good. And yes, you need to install new matching valve springs with whatever your choice is.
