Simplify Your 1965-1970 Chevy Impala LS Swap with MuscleRods

Designed for 1965-1970 B-Body Chevrolets, the 1965-1970 B-Body LS Conversion Kit by MuscleRods guarantees precise drivetrain alignment to eliminate vibrations and supports direct integration with 4L60E and 4L80E transmissions. Crafted in the USA from premium steel, it accommodates oil pans with extra clearance and delivers reliable performance under demanding driving conditions.

MuscleRods LS Engine Swap Kit for 1965-1970 Chevy Impala

Planning an LS engine swap in your 1965 to 1970 Chevy Impala often brings challenges around fitment and drivetrain geometry. The 1965 to 1970 B Body LS Conversion Kit from MuscleRods delivers precisely engineered engine and transmission mounts, plus a crossmember that ensures the factory tunnel requires no cutting or modification. Each component is crafted from high grade materials for lasting durability and keeps vibration levels in check through maintained drivetrain angles. With direct compatibility for 4L60E and 4L80E transmissions and clearance for most oil pans, this kit serves as a drivetrain alignment solution for classic Chevy builds.

Precision Engine and Transmission Mounts Ensuring Drivetrain Alignment

The 1965-1970 B-Body LS Conversion Kit features motor and frame brackets that have been engineered to hold the LS engine and transmission in exact relation to the factory driveline. By preserving the original drivetrain angle, the mounts minimize vibration feedback into the chassis and reduce stress on universal joints and couplings. This precise alignment fosters smoother power delivery under acceleration and helps protect driveline components from premature wear. Technicians will find that the components drop directly into place without guesswork, ensuring consistent results from one installation to the next.

Rugged Construction Using High Grade Materials

Every bracket and crossmember is crafted from thick, laser-cut steel that resists deformation under load and heat cycling. These parts undergo a rigorous finishing process to resist corrosion and maintain structural integrity even when exposed to road debris and moisture. The choice of material and manufacturing method delivers a level of durability that stands up to aggressive street or track use. Users can count on stable engine support without worrying about bracket flex or fatigue over time.

Crossmember and Oil Pan Clearance for Modern LS Engines

The included transmission crossmember has been designed to clear most Gen III and Gen IV LS oil pans when paired with a high clearance pan option. Its profile allows direct fitment of 4L60E or 4L80E transmissions while maintaining correct driveshaft angles. By eliminating the need to modify the tunnel or alter the chassis, builders save time and preserve structural strength. This approach opens the door to popular oil pans such as the Moroso high clearance unit or the cast aluminum retro pan without fitment headaches.

Complete Hardware Package for Hassle Free Assembly

This swap kit arrives with every nut, bolt, spacer and mount required for engine and transmission installation. By bundling the motor mounts, frame brackets, crossmember outer supports, polyurethane transmission mount, and a dedicated hardware pack, the kit ensures builders won't scavenge for parts mid-assembly. Even those new to LS conversions will appreciate that no additional drilling, cutting or reinforcement is needed to secure the powertrain. All components are numbered and supported by clear instructions, making the project both straightforward and reliable.
