Get that Gen III Hemi swap started the right way, by using a fully engineered engine & transmission mounting system that provides maximum component clearances, ideal drivetrain geometry, and clearance for Hooker BlackHeart swap headers & 3.00"" exhaust system. This transmission adapter bracket works with the modular crossmember BHS572 to fit the NAG1 automatic transmission. This design allows future transmission changes by swapping out only the transmission adapter bracket instead of replacing the whole crossmember. The crossmember (available separately) and this adapter bracket works with engine mounting brackets (available separately) for optimal engine placement to allow Short Runner Valve Clearance (eliminates modifications to the firewall & brake booster). Hooker BlackHeart swap headers & exhaust systems (available separately) are designed as part of the swap system & provide clearance with all of the transmission options.

  • Transmission Adapter Accommodates Popular NAG1 Automatic Transmissions
