Hooker BlackHeart headers are part of a comprehensive Gen III Hemi swap system that works in combination with engine mounts, transmission crossmember, and exhaust systems. BH2358 headers are packed with value added features that will make your 1966 -1972 Mopar B-Body Hemi swap easier than ever. With BH2358 headers you can use popular transmissions with either left or right hand starters (starter can be installed without removing the headers), and they clear the bulky factory power steering box with no modifications. Installing low mount A/C compressor will require the use of a VVT (variable valve timing) front drive system (2009 & Up VVT accessory drive front cover). BHS2358 headers are designed for a simple installation that provides the most ground clearance possible, and clears the popular torsion bar front suspension. The 304 stainless steel hand welded construction looks great and will last a lifetime.

  • The resulting vehicle is identical (with regard to all emissions related parts, engine design parameters and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis
  • The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
  • An EO legal engine swap kit is utilized (such as a GM EROD)
  • The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street
