MuscleRods LS Engine Swap Kit for 1964-1967 A-Body Chevelle El Camino GTO Tempest Cutlass Skylark
Installing an LS V8 into a 1964-1967 A-Body Chevelle, El Camino or Skylark often means wrestling with engine to frame alignment and tight clearances. The 1964-1967 A-Body LS Conversion Kit by MuscleRods takes that guesswork out of the process with precision laser cut brackets designed to match Chevelle El Camino GTO Tempest Cutlass and Skylark frame rails. It integrates polyurethane bushings to control vibration and maintain the GM recommended crank to driveshaft angle while preserving room for deep sump oil pans. Installers also get plug in compatibility with 4L60E and 4L80E transmissions without any tunnel modifications so that projects spend less time on mock up and more time on final assembly.
Precision Laser Cut Steel Engine Mount Brackets
The engine mount brackets are formed by laser cutting heavy gauge steel plate to match the exact profile of 1964 through 1967 A Body frame rails. This method yields tight dimensional tolerances so the LS block drops into place at the factory recommended crank to drive shaft angle without any night time fitting or manual trimming. By preserving the original alignment the design ensures smooth torque transfer and reduces stress points on the chassis rails. Builders will notice a drastic cut in mock up time as each bracket locks the block into its ideal position with repeatable accuracy. This approach also spreads load evenly when the engine applies torque or during sudden deceleration, which helps maintain chassis longevity.
Polyurethane Bushing System for Vibration Isolation
Durable polyurethane bushings bind securely between each bracket and the engine block to absorb vibration and engine movement without degrading under heat or oil exposure. Unlike rubber inserts old enough to crack or deform over time, these bushings maintain their shape and resilience even under sustained load. This stability keeps vibration levels low in the cabin and retains the ideal drivetrain angle for smooth operation of universal joints. Grade eight bolts lock the assembly in place with high clamp force that resists loosening during high output runs. The result is a consistent, quiet ride that does not compromise on performance or strength.
Integrated Transmission Crossmember for Direct 4L60E and 4L80E Fit
The one piece transmission crossmember and matching outer brackets attach to original frame holes on the A Body chassis without any tunnel trimming or modification. Included spacers allow fine tuning of crossmember height and angle to achieve perfect yoke alignment between common GM automatics and the drive shaft. Correct alignment reduces vibration and wear on universal joints while extending the service life of the rotating assembly. Builders also gain generous underbody clearance to use deep sump and high capacity oil pans without interference. The design makes installation straightforward for both professional shops and home enthusiasts, cutting down on guesswork and assembly time.
