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. BH23104 headers are packed with value added features that will make your 1973 -1974 Mopar A-Body Gen III Hemi swap easier than ever. These headers can use popular transmissions with either driver or passenger side starters, and the starter can be installed without removing the headers, and they clear Borgeson Power steering boxes 800126 or 800127. 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.
