MuscleRods LS Engine Swap Kit for 1963-1967 Chevy C2 Corvette Stingray
MuscleRods designed the 1963-1967 Corvette LS Conversion Kit to solve the common fit and alignment headaches that come with installing an LS engine in a C2 Stingray. Precision cut steel brackets tie into factory frame rails and hold the motor at the exact geometry needed for a smooth, vibration free ride. Hardware for 4L60E and 4L80E transmissions fits without modifying the tunnel or steering components. Bracket spacing clears power assist steering pumps and allows the use of high clearance or F Body oil pans with no extra fabrication.
Tailored Frame Bracket Architecture for Chassis Strength
The kit's precision cut steel brackets mate directly to the Corvette's original frame rails, creating a continuous load path that reinforces the structure under acceleration and cornering forces. By aligning the mounts with factory geometry, the system not only secures the LS engine in the optimal position but also minimizes chassis flex for improved steering feedback. Each bracket is laser cut for repeatable accuracy, ensuring a uniform fit across all 1963–1967 C2 models without the need for trial fitting or off-site machining. This integrated approach preserves the Corvette's sheetmetal and factory rail design while elevating the car's overall rigidity.
Polyurethane Transmission Mount for Vibration Isolation
The included transmission mount is molded from a resilient polyurethane material chosen for its blend of stiffness and shock absorption. This compound resists oil and coolant exposure, guaranteeing that the mount maintains its damping properties over countless heat cycles. When fitted into the crossmember bracket, the polyurethane insert filters engine and driveline harshness, delivering a smoother ride and reducing cabin noise. Installers will appreciate how the mount seats cleanly into place with no need to modify the tunnel or weld new brackets.
Engine and Transmission Versatility for Custom Builds
This conversion kit has been engineered to support most Gen III and Gen IV LS engines, including LS1, LS2 and LS3 platforms, so builders can pair the powerplant that best suits their goals. The transmission crossmember bracket ships with spacers that cover both 4L60E and 4L80E bolt patterns, and it can accept a T56 with minor alignment tweaks. Bracket spacing also clears factory power steering pumps and offers the clearance required for F Body oil pans when using manual or late-model steering boxes. That flexibility lets you mix and match engine, steering and pan options without cutting or welding the original tunnel.
