460 Ford Cast Aluminum Exhaust System - Manifolds Only

620-36001

460 Ford Cast Aluminum Performance Exhaust System - Manifolds Only, (Includes Bolts & Gaskets)

The long awaited and much anticipated new Performance Ford center rise exhaust systems are now available from Hardin Marine. Hardin adapted the same technology used to develop the powerful manifold systems found on Mercury Racing’s HP500 and 540 Bulldog engine packages and integrated that individual separated runner design into this new Big Block Ford exhaust system. Hardin knew while perfect for direct replacement these also compliment today’s larger custom Ford 500 CID plus engines. These engines require an exhaust system that not only scavenges, but can also expel the massive amounts of exhaust created by these larger engines while reducing exhaust back pressure to near non-existent levels. These manifolds are cast from pure T356 aluminum and then heat treated to a T6 condition. The final steps include hard anodizing for corrosion resistance and a gloss powder coated for a stunning appearance. Individual exhaust ports are cooled by a balanced and even water flow thru the manifold. Exhaust tailpipes are available in a standard exit or custom applications and are constructed from quality 316L stainless steel.

  • 35" Overall Width on stock heads.
  • 29-1/2" Exhaust Center to Center on stock heads.
  • 8" Tall from Exhaust center-line to top of manifold on stock heads.
  • 12-3/4" Tall from Exhaust center-line to top of riser on stock heads.
