Now that Im getting a new motor, time for a new cam. Its a 331 setup, with stock heads and a professional products intake. I had a stock cam with my old setup and seemed to work pretty good, but I think Im looking for a little bit more "thump". Was looking into the "F" cam, but that seems to be like 10+yr old technology so Im sure there are some better choices. Any suggesstions...?? Thanks.
