My motor took a crap in my 68 camaro now im looking into getting the zz383 crate motor. my old motor was a solid cam and it had a nice lope to it. I hear cars with zz383 on youtube and they dont sound to aggresive. I was wondering what would be a good cam choice for some aggresive lope and a increase in power. I like the sound of the thumpr cams but not sure which to get.
