Engine Mounts Mopar Hemi for K Member

The QA1 Engine Mounts Mopar Hemi for K Member (Part No. 7740-335) is a bolt-on motor mount solution engineered for Mopar Gen III Hemi engine swaps into classic B-Body and E-Body platforms from 1966–1974. Constructed from steel with a durable black powder coat finish, this pair of mounts delivers the structural rigidity and vibration isolation required to secure modern Hemi powerplants within vintage chassis geometry without compromise.

QA1's conversion mount design addresses the primary engineering challenge of modern engine transplants: matching contemporary engine mounting points to original K-member configurations. The steel construction resists the thermal cycling and mechanical stress inherent to high-output Hemi engines, while the powder coat protects against corrosion and cosmetic wear in engine bay environments. Each mount weighs 8.75 lbs and measures 12.2 x 6.9 x 12.2 inches, making them compatible with the OEM K-member attachment points on B-Body and E-Body vehicles. The bolt-on design eliminates the need for extensive fabrication, reducing installation time and maintaining frame integrity.

This product serves restomod builders, classic car enthusiasts, and performance shops executing Hemi engine conversions on second-generation Dodge and Plymouth muscle cars. The mounts isolate engine vibration from the chassis while maintaining alignment under acceleration loads—critical for vehicles pushing modern horsepower through original suspension geometry. The pair configuration ensures balanced load distribution across both engine mounting points, preventing frame flex and drivetrain binding.

Mopar engine swaps demand precision-engineered mounting solutions that respect original frame design while accommodating larger, heavier powerplants. QA1's conversion mounts are purpose-built for this application, offering a tested alternative to custom fabrication on platforms where off-the-shelf solutions are limited. Whether upgrading a 1970 Dodge Charger or 1972 Plymouth Cuda, these mounts provide the foundation for reliable long-term Hemi integration.
