Hooker Blackheart engine swap mounts allow easy installation of the Gen III Hemi engine in your 1970-1974 Dodge Challenger amd Plymouth Barracuda (Mopar E-Body). These engine-mounting brackets are part of an engineered solution that works together with the transmission crossmember and headers to optimize the engine placement and component clearances along with ideal drivetrain / U-joint operation angles.
The engine placement eliminates modifications to the firewall and the engine mount brackets fit the K-member on cars that originally came from the factory with a V8 engine. Clearance was provided for the Short Runner Valve (SRV) intake solenoid, low mount alternator and low mount A/C Compressors when used with a VVT (Variable Valve Timing) accessory drive.

Hooker BlackHeart transmission crossmembers are a part of the most comprehensive line of Gen III Hemi swap components available for the Mopar E-Body. This crossmember allows the installation of the popular A727 3-speed automatic, NAG1 5-speed automatic and 8HP70/8HP90 8-speed automatic transmissions, or the Tremec TKX (GM style) six-speed manual transmission when used with the corresponding adapter plate (sold separately). No cutting or drilling is necessary; just bolt it in the OEM location using the supplied hardware.
The modular design allows the use of several different transmission options without the need to buy or fabricate a different crossmember – simply change to a different adapter plate and the driveline and u-joint alignment have been preset to the corresponding transmission. The BHS567 crossmember is designed to use a popular and inexpensive GM style transmission mount for its compact design that allows for better ground clearance than the OEM crossmember (Hooker part number 71223029HKR or 71223030HKR – sold separately). Solid 3/16″ Steel construction and a black coated finish provides long lasting performance and good looks.
