I just read on another forum about a set of road racing cams for the 4.6 3 valve. There due to be released soon, they make 30 hp and 20 foot pounds on a stock motor. They make 75 hp and 46 foot pounds with ported heads. They had a sound clip from youtube, they sounded good. Has anyone else heard of these new ford cams? The numbers look pretty impressive for a set of cams.
