      Will this engine fit in my 70 Shelby

      Asked by: TLT59
      It may fit the only concerns you may have are the oil pan, headers an motor mounts. Front or rear sump oil pan? Headers, Mid, Original, Long tube? Motor mount locations? These are the big question you'll need to address, to insure a fit.
