MuscleRods LS Engine Swap Kit for 1964-1967 A-Body Chevelle, El Camino, GTO/Tempest, Cutlass/442, Skylark
Swapping an LS engine into a 1964-1967 GM A-Body chassis often triggers clearance conflicts and powertrain misalignment; the 1964-1967 A-Body LS Conversion Kit from MuscleRods provides precision frame brackets and motor mounts that eliminate guesswork. Built in the USA from cold rolled steel with urethane bushings and grade 8 hardware, it maintains the drivetrain angle and supports both 4L60E and 4L80E transmissions without modification. Detailed bracket geometry accommodates high clearance oil pans from manufacturers like Moroso while preserving frame rail strength and ground clearance for both restoration and performance applications.
Precision Frame Bracket Geometry for A Body Chassis Alignment
This kit features custom frame brackets shaped to exact factory dimensions for 1964 to 1967 A Body models. By matching the original rail contours, the engine maintains its ideal drivetrain angle and reduces unwanted vibration. The CNC formed brackets eliminate the need for time consuming adjustments and ensure consistent power delivery. This results in smoother start up, refined throttle response and improved serviceability when fine tuning the engine position.
Seamless Integration with GM 4L60E and 4L80E Transmissions
The conversion process becomes straightforward thanks to the ready to install transmission crossmember and mount components that work with both GM 4L60E and 4L80E gearboxes. Installers can position the output housing at the correct height without modifying the tunnel, saving time on trial fits. Using the supplied polyurethane transmission mount secures the gearbox and supports precise driveline alignment. This approach minimizes installation errors and lets builders focus on wiring and plumbing details.
Robust Cold Rolled Steel and Urethane Bushing Construction
All brackets are laser cut from 1/4 inch cold rolled steel, providing the strength to handle modern LS torque levels. Strategic placement of urethane bushings at key attachment points isolates engine movement and dampens harsh vibration for a quieter cabin. Assembly hardware includes grade 8 bolts and washers that offer high tensile strength and fatigue resistance under repeated load cycles. The combination of heavy metal and engineered elastomer elements balances rigidity with noise and vibration control for lasting reliability.
Versatile Compatibility with Gen III and Gen IV LS Engine Variants
Designed to clear high clearance oil pans and aftermarket intake manifolds, this kit accepts popular Gen III and Gen IV LS engine configurations including LS1, LS3, 5.3 liter and 6.0 liter units. Bracket geometry accommodates pans from leading manufacturers to preserve ground clearance and protect the sump during spirited driving. This flexibility allows enthusiasts to choose performance components without concern for fit issues inside the A Body frame rails. Whether fitting a compact small block or a big bore engine, the kit delivers consistent service access and installation confidence.
