MuscleRods LS Engine Swap Kit for 1958-1964 Chevy Impala
When fitting a modern LS motor into a 1958 to 1964 Impala B-Body project, the 1958-1964 B-Body LS Conversion Kit eliminates guesswork at the mounting stage by securing the engine and transmission crossmember to factory rails without modifying the transmission tunnel. It holds the powertrain at factory specified angles to prevent vibration and reduce wear on universal joints and transmission bearings under load. By aligning with common LS oil pan profiles used on F Body engines and offering direct bolt in brackets, MuscleRods ensures adequate hood clearance and streamlines plumbing and wiring tasks. Support for T56, 4L60E and 4L80E transmissions further reduces mockup sessions and keeps installation time to a minimum.
Factory Specified Alignment for LS Drivetrain
The kit secures the LS engine and transmission at factory specified angles to prevent vibration and reduce stress on universal joints and main bearings. By using calibrated spacers and precision laser cut brackets, it achieves exact geometry without multiple test fits so builders can skip lengthy trial and error. Correct drivetrain alignment enhances smooth operation at low speeds and curbs harsh feedback under load. This meticulous approach also extends the longevity of drivetrain components by keeping forces within design tolerances.
Direct Integration with B Body Frame Rails
Each motor mount and bracket is laser cut from high strength steel to bolt directly into the original 1958 to 1964 B Body side rails. This eliminates the need for cutting or reshaping the floor structure and simplifies installation. The preformed mounting points align with the factory transmission tunnel, preserving interior floor integrity and ensuring adequate clearance for an F Body style oil pan. Builders benefit from a streamlined fit and reliable joint integrity thanks to the supplied hardware pack featuring grade 8 fasteners.
Versatile Transmission Compatibility and Future Adaptation
With built in support for T56, 4L60E and 4L80E transmissions, this solution offers flexibility for a broad range of LS swap projects. It accepts common bolt patterns on most third and fourth generation LS engines when paired with an F Body oil pan and appropriate intake manifold for hood clearance. That adaptability removes the need for additional adapter plates in many cases while maintaining efficient power flow and minimal vibration. Whether the priority is higher output or stock feel performance, the kit accommodates future engine and gearbox upgrades with confidence.
