Although these systems have been specifically developed for direct fitment with HOOKER (TM) LS swap components for these applications, they will provide equally beneficial fitment, function, and service life with other non-Hooker LS swap manifolds/headers. Can easily be made to work on non-LS engine-equipped G-bodies through modification of the system inlet tubes, or construction of new ones by a competent fabricator. |
