1964-67 A-Body LS Engine Swap Solution by MuscleRods

Built with precision mounts and brackets custom fit for 1964 to 1967 GM A Body models, this LS conversion kit eliminates clearance issues and aligns the drivetrain correctly for smooth, quiet performance. MuscleRods ensures plug and play compatibility with 4L60E and 4L80E transmissions and supports high pans for increased ground clearance while USA assembly guarantees lasting durability.

MuscleRods LS Swap Kit for 1964-1967 A-Body Chevelle El Camino GTO/Tempest Cutlass/442 Skylark

When you set out to install a modern LS powerplant in a classic GM A Body from 1964 to 1967, the 1964 to 1967 A Body LS Conversion Kit ensures an exact fit without guesswork. This engine swap kit from MuscleRods uses precision frame brackets and engine mounts to maintain correct drivetrain angle and clear a high clearance oil pan. Constructed in the USA from durable cold rolled steel with urethane bushings and grade 8 hardware, it integrates seamlessly with 4L60E and 4L80E transmissions for a straightforward installation process.

Precision Engineered Fit for A Body Drivetrain Alignment

This LS swap kit employs custom frame brackets and motor mounts machined to exact tolerances, ensuring the engine sits at the proper drivetrain angle. By maintaining the correct alignment, vibrations that often arise from misaligned powerplants are dramatically reduced, resulting in smoother acceleration and refined ride comfort. The mounting points are CNC formed to mirror the 1964-1967 A Body chassis dimensions, eliminating geometry adjustments that can cost time and introduce error. Installers benefit from an exact fit that preserves factory suspension dynamics while unlocking the potential of modern LS power.

Seamless Integration with GM 4L60E and 4L80E Transmissions

Designed for plug and play compatibility, this conversion kit accommodates both 4L60E and 4L80E transmissions without requiring modifications to the transmission tunnel. The included crossmember and polyurethane transmission mount position the gearbox at the optimal height and orientation, simplifying alignment with the driveline. Hobbyists will appreciate the elimination of trial and error when bolting up the transmission, allowing focus on wiring and plumbing rather than cutting or welding. This straightforward approach reduces labor time and ensures the powertrain operates with factory-level precision.

Heavy Duty Steel and Urethane Bushing Construction

All mounting brackets are laser cut from 1/4 inch cold rolled steel to deliver the rigidity needed for high torque output. Urethane bushings are employed at key attachment points to isolate engine movement and dampen harsh vibrations, preserving both component life and cabin refinement. Assembly hardware includes grade 8 bolts and washers, offering superior tensile strength and resistance to fatigue under repeated load cycles. By combining robust metals with engineered elastomers, this kit balances durability with NVH control for lasting performance.

Design for High Clearance Oil Pan Compatibility

The bracket geometry and frame rail clearance are optimized to accept high clearance oil pans, such as the Moroso option, without additional trimming. This design consideration delivers improved ground clearance and protects the sump from impacts when driving on uneven surfaces. It also accommodates a range of Gen III/IV LS engines-LS1, LS3, 5.3L and 6.0L-alongside performance intake manifolds that often add height under the hood. Enthusiasts gain the freedom to choose both engine and oiling solutions without compromising fitment or service access.
