    Important Installation Notes:

    • Integral part of the Complete Hooker swap system for this application. Components feature unique design geometry that is not compatible with any other brand of transmission crossmember or headers.

    • Installation of these brackets requires the installation of new stock OE style clamshell engine mounts (Anchor/Westar 2292 mounts or aftermarket poly inserts), as installed on all 1978-88 A/G-body vehicles equipped with Chevrolet small block V-8 engines. Do not reuse old clamshell mounts as part of this installation.

    • When used with the related Hooker p/n 520-12644 transmission crossmember, this CAD designed engine swap mounting bracket kit will replicate the stock small block Chevy engine/transmission inclination angle in order to minimize the need to shim/adjust the rear pinion angle in stock to moderately lowered chassis applications.

    • Due to the unique design geometry of this engine swap mounting bracket kit, attempts to install it with headers and/or transmission crossmembers not developed by Hooker for this application will more than likely not be successful.

    • An engine hoist will be required to position the engine/trans into the vehicle in the proper orientation. Use of an adjustable-angle engine sling will greatly ease the hoisting/loading operation and negate the possible need to reposition the lifting chains mid-operation. An automotive lift or a jack and jack stands will be required to safely raise and support the vehicle.

    • If you are intending to retain the functionality of the stock A/C system, it is highly recommended that you install the engine and transmission into the vehicle separately to minimize the chance of damaging the evaporator case on the firewall when positioning the engine in the chassis. Due to the extremely large production tolerances across all year models of these vehicles, clearance between the right side valve cover and the evaporator case can range from 1/2'' to 0 distance between these components; some installations will provide a surplus of coil/coil bracket clearance while others will be tight and require the rear coil to be relocated away from the evaporator case for clearance.
