460-454 Ford to Chevy Jet boat Exhaust Billet Aluminum Adapter Plates

Description

460-454 Ford to Chevy Jet boat Exhaust Billet Aluminum Adapter Plates.   Run Chevy headers on that Ford 460 ford.  Should also work on the 429.
Chevy headers are a better free flowing design and easier to find
These are a bare port meaning they match up to a ford  stock exhaust port.  To get a perfect match some sanding maybe be required but not necessary to run.  There is also enough material here match cobra jet heads also.
I switched from thru transom exhaust to this set up on bone stock (dv3e) heads and Gained 300 rpm and 3 mph in my boat.
I recommend high temp silicone for the mating surfaces.
Comes with a Drivers side and a passenger side plus SS cap head screws for mounting.
