MuscleRods LS Power for Your 1968-1982 Chevy C3 Corvette

Delivering precision-engineered mounts, brackets built in USA and versatile oil pan options, the MuscleRods 1968-1982 Corvette LS Conversion Kit ensures a seamless LS integration in your C3 Shark chassis. Installers benefit from accurate drivetrain alignment, a design that avoids transmission tunnel cuts for your 4L60E swap and delivers smooth driving comfort so you can modernize your Corvette with confidence.

MuscleRods LS Engine Swap Kit for 1968-1982 Chevy C3 Corvette

When integrating an LS powerplant into your 1968-1982 C3 Corvette, finding engine mounts and crossmembers that align perfectly with factory frame rails can be a time consuming task. The 1968-1982 Corvette LS Conversion Kit delivers precision machined brackets and a transmission crossmember to simplify installation and maintain proper driveline angles for smooth operation. Developed by MuscleRods, the package also allows for various oil pan configurations and supports popular transmissions like the 4L60E without modifying the transmission tunnel.

Precision Engine Mounts for Seamless LS Integration

The 1968-1982 Corvette LS Conversion Kit features precision engineered engine mounts that align the LS block exactly within the C3 frame rails. By replicating the OEM mounting geometry with close tolerance brackets, it eliminates the need for trial fitting or aftermarket modifications. Each of the two motor mounts is crafted to absorb torque forces while preserving engine position under load, ensuring a stable foundation for your LS powerplant. The robust construction translates into consistent fitment across compatible Gen III and Gen IV engines.

Drivetrain Angle Optimization for Smooth Operation

A key benefit of this kit is its attention to driveline geometry, maintaining the factory designed pinion angle to minimize vibration throughout the powerband. Correct transmission placement reduces stress on universal joints and prolongs component life, delivering a smooth driving experience from idle to full throttle. The integrated design keeps the engine and transmission centers in perfect alignment, which also enhances torque delivery and throttle response. Enthusiasts will appreciate the subtle yet noticeable improvement in drive quality and longevity.

Transmission Crossmember Designed for Tunnel Preservation

The included transmission crossmember bracket and spacer set work in concert to support popular transmissions like the 4L60E without modifying the transmission tunnel or chassis. The custom bracket anchors directly to factory frame openings, while the two crossmember spacers fine tune the height for an exact fit. A durable polyurethane transmission mount secures the transmission housing, dampening vibration and isolating driveline noise. This approach simplifies installation and preserves the Corvette's original structural integrity.

Versatile Oil Pan and Steering Clearance Adaptability

Whether you retain the factory power steering system or convert to manual steering, this kit accommodates multiple oil pan configurations. It supports the clearance pan often used in F Body applications as well as the standard GM design, ensuring adequate space under the steering box. This adaptability removes the need for any steering modifications and allows builders to choose a pan that matches their driving setup. Proper pan selection combined with the kit's engineered fitment keeps oil pickup safe and reliable, even under spirited driving conditions.

This is not an add on but a more robust kit that lets you select parts to better suit your needs. For that option see our Complete LS Swap Kits - LS Kit Builder.
