I asked a noted Tech Ed. of a big name Mustang mag,if he could give me any cam and head specs. on the 01 GT 2V mod motors. Nope,he didn't have a thing on them. Hmmmmm,bet if I wanted to know the specs. on any Supercharger,I would have volumes of info.! Why is there no easily found info. on these engines.....especially the Bullitt? You know 20-30 yrs. back,they used to come out with Engine Annuals,describing the latest hot engines out of Detroit.I think Hot Rod mag and Cars mag. used to do that.
