I just purchased a hoard of Mustangs. A 1967 Shelby fastback clone, a 1967 convertible and a Ford drag car frame with a very highly modified 289. I'm not a Ford expert and I'm trying to determine if any of these engines are the famous "289 hipo." Can anybody here please explain to me in painful detail how I can tell hipo heads, intakes, blocks, etc etc etc? from regular a or c code engines?
