Complete MuscleRods LS Engine Swap Kit for 1968-1974 Chevy Nova and Pontiac Ventura
If you plan to drop an LS motor into a classic Nova or Ventura X Body from 1968 to 1974 this Nova LS Conversion Kit is designed to handle tilt angle and oil pan clearance issues. Next the precision CNC machined motor mounts hold the engine at its factory tilt and match the driveshaft yoke alignment to minimize vibration and component wear. With a reinforced steel crossmember and brackets for T56 4L60E and 4L80E transmissions installers gain correct height above the frame rails without modifying the tunnel or chopping the floor pan. Components are made in the USA under strict inspection protocols to ensure reliable fitment and smooth installation while delivering consistent drivetrain alignment across every build.
Precision CNC Machined Motor Mounts for Factory Tilt Accuracy
These motor mounts are crafted using advanced computer numerical control machining to secure the LS engine at its original factory tilt. By matching the small block Chevy inclination, the kit preserves proper pinion yoke alignment and prevents side load on universal joints. As a result, vibration transmitted through the frame is minimized and engine rotation remains smooth under throttle. Installers gain a repeatable fit that eliminates the need for shims or trial adjustments, greatly simplifying setup. Accessory brackets align precisely, reducing the time required for engine assembly. This engineered alignment also reduces the need for custom driveshaft angles and knock sensor adjustments.
TIG Welded Steel Crossmember for Robust Transmission Support
Fabricated from heavy gauge steel with TIG welded seams at critical load points, the crossmember resists flex under high torque conditions. It positions T56, 4L60E, and 4L80E transmissions at the correct height, clearing the stock tunnel without any cutting or reshaping. A polyurethane mount cushions torque shifts, softening noise and harshness during rapid acceleration and deceleration. Machined bracket faces and spacers maintain exact tail housing alignment, preventing binding and preserving driveshaft geometry. The steel structure aligns perfectly with frame contours to retain original ride geometry. This reinforced design stands up to modern LS power, delivering consistent performance mile after mile.
High Clearance Oil Pan Adaptation Preserves Chassis Integrity
The kit raises the oil pan above the frame rails to maintain ground clearance and full suspension travel while accommodating high clearance or cast aluminum sumps. Engineers verified that exhaust routing remains free of interference and that steering linkages operate without restriction at full lock. By avoiding any modification to the transmission tunnel or floor pan, the original X Body structure stays intact. Builders can install a variety of aftermarket sump options without additional fabrication, offering greater flexibility for performance builds. This approach delivers modern oil retention benefits without sacrificing ride height or handling balance. Routine sump service remains straightforward thanks to the unobstructed design.
Complete USA Built Kit with All Required Hardware
Every element needed to mount an LS engine and compatible transmission is included, from motor mounts and frame brackets to crossmember spacers and a polyurethane transmission mount. Domestic production under strict quality controls ensures each CNC machined surface meets tight tolerances and welded assemblies are verified for strength. A detailed instruction guide walks installers through each phase, from initial frame crossmember placement to final torque settings. With this all inclusive solution, builders avoid extra trips for parts and achieve a consistent outcome on every Nova or Ventura swap. By delivering a single cohesive package, the kit eliminates guesswork and fits all specified GM models with a factory style appearance. This unified design streamlines installation and provides confidence in long term reliability.
