MuscleRods LS Engine Swap Kit for 1968-1972 A-Body Chevelle/El Camino/GTO/Cutlass/442/Skylark
When retrofitting a modern LS engine into a 1968-1972 GM A-Body chassis, fitment and alignment challenges can derail the swap, and the 1968-1972 A-Body LS Conversion Kit solves these with precision engineered engine mounts and a purpose built crossmember. It maintains the factory drivetrain angle and clears both 4L60E and 4L80E transmissions without altering the tunnel walls. Built by MuscleRods in the USA, this Engine Swap Kit also provides room for a high clearance oil pan while reducing driveline vibration for smoother, quieter performance. With vehicle specific brackets for Chevelle, El Camino, GTO, Cutlass and Skylark, installation is straightforward and reliable.
Maintaining Factory Drivetrain Angle
This kit features custom motor mounts and a purpose built crossmember designed to hold the engine and transmission alignment exactly as GM intended. The rigid brackets resist torque from LS powerplants, preventing driveline vibration and extending u joint and driveshaft life. By preserving the original angle builders gain quiet smooth operation across the entire rpm range. Installers avoid the usual chassis modifications and alignment shims that often add complexity and noise.
Direct Fit for 4L60E and 4L80E Transmissions
Engineered for direct fit with 4L60E and 4L80E transmissions, the included crossmember and brackets align precisely with the A Body floorpan without cutting or reshaping. Built in clearance for an oil pan with extra room allows a wide selection of intake manifolds without interference under the hood. The polyurethane mount and spacer kit isolates noise and absorbs vibration, keeping the cabin quiet. This straightforward transmission fitment cuts out hours of test fitting and ensures reliable engagement.
Efficient Bolt In Swap with Precision Formed Mounts
All components arrive ready to install, from motor mounts and frame plates to the transmission crossmember and hardware pack. Each piece is laser cut or cnc formed to factory spec, so fits are exact and eliminate guesswork during installation. Even less experienced mechanics can bolt in an LS engine quickly without trial and error, saving hours of labor. The clear instructions and precise fitment streamline the process for hobbyists and professionals alike.
Rugged Made in USA Construction
Brackets and mounts are manufactured in the USA from heavy gauge steel and finished with a durable powder coat for outstanding corrosion resistance. Weld seams are performed by certified technicians using a TIG style process to guarantee structural strength under repeated torque cycles. This robust fabrication ensures the kit stands up to road grit, weather, and long term use. Users can trust the quality and consistency of components built to tight tolerances.
