1968-1974 Chevy Nova/Ventura X-Body LS Swap Kit by MuscleRods

Achieve optimal drivetrain alignment in your LS conversion for a 1968-1974 Chevy Nova or Ventura X Body thanks to precision machined steel mounts, brackets and hardware that maintain factory fit while protecting vital engine components. The all inclusive MuscleRods kit accommodates T56, 4L60E and 4L80E transmissions without tunnel modifications, preserves high clearance oil pan space and delivers a comfortable, vibration free ride with American made craftsmanship you can trust.

MuscleRods LS Engine Swap Kit for 1968-1974 Chevy Nova and Pontiac Ventura X-Body

Bringing LS performance to a classic 1968-1974 Chevy Nova or Pontiac Ventura X Body chassis means wrestling with tilt angle and pan clearance, and the 1968-1974 Nova LS Conversion Kit answers those needs. With precision CNC machined motor mounts and a reinforced steel crossmember, the kit secures the engine at the factory tilt while clearing the oil pan above the frame rails for smooth suspension travel. Installation follows detailed instructions and includes every bracket, spacer, and bolt required to fit T56, 4L60E or 4L80E transmissions without modifying the tunnel. Built in the USA and engineered to deliver correct drivetrain angle, it reduces vibration and drivetrain stress for a refined driving feel in your restored X Body.

Precision Engine Mounts for Accurate LS Drivetrain Alignment

The kit's engine mounts are crafted through computer numerical control machining to hold LS powerplants at the original factory tilt. This precision fit ensures the driveshaft remains in perfect alignment with the pinion yoke, reducing torsional stress on universal joints and differential bearings. By eliminating the need for field shimming, builders achieve a smooth power delivery and lower vibration levels throughout the driveline. The accuracy of these mounts also simplifies the installation of accessories, making accessory bracket alignment predictable and repeatable. Enthusiasts will notice a refined throttle response and extended service life for drivetrain components.

Reinforced Steel Crossmember for Transmission Support

Constructed from heavy gauge steel, the transmission crossmember features TIG welded reinforcement at high-stress junctions to withstand torque loads without flexing. It positions T56, 4L60E and 4L80E transmissions at the correct height above the frame rails, eliminating the need to modify the tunnel for clearance. A molded polyurethane mount cushions sudden load shifts, reducing noise and harshness under acceleration. Precision spacers guarantee tail housing placement remains consistent from build to build, preventing premature wear of universal joint bearings. The robust design maintains structural integrity even under demanding driving conditions.

Elevated Oil Pan Clearance to Preserve Ground Clearance

This conversion solution raises the oil pan above the frame rails to clear obstacles and preserve the ride height of classic X Body chassis. It accommodates modern high clearance or cast aluminum sump pans while fitting neatly within the transmission tunnel contour. Engineers validated full suspension travel and ensured exhaust routing remains unhindered without cutting or modifying steering components. The layout prevents interference between intake runners and steering linkages under full steering lock. Drivers benefit from modern oil containment geometry without sacrificing clearance or chassis reliability on rough road surfaces.

Complete American Manufactured Installation Components

All brackets, mounts and spacers are produced in the United States under strict quality control standards to deliver consistent dimensional accuracy. CNC machined surfaces are inspected for tolerance while welded assemblies undergo visual and measurement checks for structural soundness. The hardware pack includes every bolt, spacer and nut required for a seamless fit with T56, 4L60E or 4L80E transmissions, eliminating trips to supply stores. Detailed step-by-step instructions guide installers through engine and transmission installation without guesswork. This comprehensive approach ensures first-time fitment success and long-term reliability in your restored 1968-1974 Nova or Pontiac Ventura X Body.
