Hooker Headers BH2390 BlackHeart Gen III Hemi Swap Mid-Length Headers
Thank you for choosing to use HOOKER™ headers as part of your GEN 3 HEMI swap project. These headers are part of the most comprehensively engineered system of mounting components, headers, and exhaust systems available for this application. The entire Hooker™ swap system is designed to decrease your total swap installation effort and cost while increasing the engineered quality of your vehicle.
PRE-INSTALLATION CONSIDERATIONS
Check that the hardware package includes the following:
Qty. Description
12 M8 x 1.25 Header Bolts
If you are missing any hardware, please contact Technical Service at
1-866-464-6553 or
270-781-9741.
NOTE: Will not work with factory column shift linkage. Aftermarket column
linkage or cable kits such as those offered by Lokar™ and others will have to
be used if you wish to maintain the column shift capability of your vehicle.
NOTE: These headers are geometrically/functionally compatible with
Chrysler NAG 1, 8HP70, 545RFE, 46RE, 46RH, A727, and GM 4L80E/4L85E automatic
transmissions and the OE GEN 3 HEMI TR-6060 and T56 Magnum manual
transmissions.
NOTE: These headers do not possess a CARB Executive Order Exemption and
are therefore not legal for sale or use on pollution-controlled motor
vehicles.

to an exhaust system with specific-design Torca 3” coupler clamps, which are
included in the Hooker exhaust system kits for this application.
The instructions contained in this document assume you have already installed
the engine and transmission in the vehicle with the above-mentioned HOOKER™
mounting components per their instructions.
An automotive lift or a jack and jack stand will be required to safely raise
and support the vehicle. CAUTION! WORK ONLY ON A LEVEL SURFACE. USE JACKS
/JACK STANDS OF SUFFICIENT CAPACITY TO LIFT AND SUPPORT YOUR VEHICLE. NEVER
WORK UNDER A VEHICLE SUPPORTED BY A FLOOR OR BUMPER JACK.
COMPATIBILITY INFORMATION
These headers were specifically designed to be installed with HOOKER™ GEN 3 HEMI swap engine and transmission mounting components and exhaust systems for this same application. Attempts to install these headers with any other type or combination of engine and transmission mounting components may cause them to not provide their intended ground or vehicle component clearances, or compatibility with the related HOOKER™ exhaust systems. These headers are fully compatible for use with the stock A/C evaporator case. May require a small-diameter brake booster on applications such as Hellcat.
INSTALLATION

- Remove the engine oil dipstick tube.
- Remove any transmission linkage present between the transmission and steering column.
- Using an automotive lift or floor jack, lift the entire vehicle or front of the vehicle a minimum of 12” to 15” off the ground.
