Get that Gen III Hemi swap started the right way, by using a fully engineered engine mounting system that provides maximum component clearances, ideal drivetrain geometry, and clearance for Hooker BlackHeart swap headers & 3.00" exhaust system. The transmission crossmember is a modular design that allows the use of several different transmissions & uses a unique mounting bracket for each type of transmission. This design allows future transmission changes by swapping out only the transmission mounting bracket instead of replacing the whole crossmember. This crossmember works with engine mounting brackets BHS524 (available separately) to locate the engine in the optimal location to eliminate 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.
