Hooker Blackheart engine swap mounts allow easy installation of the Gen III Hemi engine in your 1973-1976 Mopar A-Body. These engine-Mount assemblies are part of an engineered solution that works together with the transmission crossmember and headers to optimize the engine placement & component clearances along with ideal drivetrain / U-joint operation angles. The engine placement eliminates modifications to the firewall and the engine mounting brackets fit the K-member on cars that originally came from the factory with a V8 engine. Firewall clearance provided for the use of Short Runner Valve (SRV) intake solenoid (no need to lock valve and sacrifice top end performance). Use with 2009 & up 5.7L, 6.2L, or 6.4L car style factory accessory drive system (variable valve timing accessory drive system with low mount alternator), or Holley Mid-Mount accessory drive system.
