Complete MuscleRods LS Engine Swap Kit for 1964-1967 A-Body Chevelle El Camino GTO/Tempest Cutlass/442 Skylark
When dropping an LS V8 into a 1964 through 1967 GM A Body chassis the task of aligning the engine to the original frame rails and transmission tunnel often consumes hours beyond expectations for even seasoned builders. MuscleRods simplifies this challenge with the 1964 through 1967 A Body LS Conversion Kit which uses precision laser cut steel brackets and polyurethane bushings to secure LS blocks and a 4L60E or 4L80E transmission at GM recommended angles without trimming metalwork. Installers benefit from generous oil pan clearance and controlled vibration thanks to bracket contours matched to factory rails and durable hardware that preserves frame integrity. As a drivetrain alignment solution this kit cuts trial fitting and lets builders focus on completing Chevelle, El Camino or Skylark builds.
Engine Bracket Design for Accurate A Body Alignment
The LS conversion brackets are formed using precision CNC laser cutting to replicate the factory frame rail contour on 1964 to 1967 GM A Body models. By securing the LS block at the exact angle recommended by GM engineers, the kit preserves original drivetrain geometry so that torque pulses transfer smoothly through the driveshaft and universal joints. This exacting fit eliminates hours of trial alignment and metal trimming, allowing installers to achieve correct placement on first attempt. Even load distribution under acceleration and deceleration reduces stress on mounts and chassis rails, contributing to consistent power delivery and long term reliability.
Cold Rolled Steel Construction with Polyurethane Vibration Isolation
Bracket components are cut from quarter inch cold rolled steel known for its tight thickness tolerance and superior yield strength compared to stamped alternatives. A protective finish guards against corrosion from road salt and moisture, extending component life in diverse climates. Bonded polyurethane bushings isolate engine motion and absorb torque impulses without deteriorating under heat or oil exposure, keeping vibration levels in check for a smoother ride feel. Grade eight plated hardware secures the assembly with exceptional clamping force that resists loosening, ensuring a snug fit even under sustained engine load.
Integrated Transmission Crossmember for 4L60E and 4L80E Support
This kit features a one piece transmission crossmember and outer brackets that bolt directly to factory mount points without any tunnel modification. Interchangeable spacers allow installers to fine tune crossmember height and angle for precise yoke alignment with the driveshaft, preventing premature universal joint wear. Maintaining correct transmission angle minimizes noise and vibration while improving service life of rotating components. Comprehensive mounting instructions and a clear hardware layout streamline the process so both seasoned shops and weekend builders can complete the installation efficiently.
Optimized Clearance for Oil Pan and Underbody Components
A generous gap between the crossmember and frame rails accommodates deep sump, performance and high volume oil pans without interference. In block oil filter locations and intake runner areas, the design leaves ample space for routine service or future upgrades, avoiding the need for custom pan or chassis modifications. The open crossmember profile also provides room for popular bolt on exhaust headers and underbody shields, preserving ground clearance for lowered suspension setups. This thoughtful engineering reduces mock up time and delivers a clean engine bay that balances classic style with modern functionality.
