Complete MuscleRods LS Engine Swap Kit for 1968-1974 Chevy Nova and Pontiac Ventura X-Body
Starting an LS conversion in a 1968-1974 Chevy Nova or Pontiac Ventura X Body often means facing tilt angle and oil pan clearance obstacles. This MuscleRods Engine Swap Kit brings precision CNC machined motor mounts and a reinforced steel crossmember to hold the LS motor at its factory tilt while clearing the oil pan above the frame rails. With included brackets, spacers and hardware for T56, 4L60E and 4L80E transmissions the kit installs without modifying the tunnel. Built in the USA, it delivers correct drivetrain angle to reduce vibration and safeguard driveline components.
Precision CNC Machined Motor Mounts for Accurate LS Angle
The motor mounts in this LS swap kit are crafted using computer numerical control machining to hold the engine at the exact factory tilt angle. By matching the original inclination of a small block Chevy, these mounts ensure the driveshaft remains aligned with the pinion yoke, reducing wear on universal joints and differential bearings. This precision fit eliminates the need for shimming or trial and error, delivering consistent alignment every time. As a result, drivers experience lower vibration levels through the chassis and a smoother power delivery under load. The accurate geometry also simplifies the placement of accessory brackets, making engine assembly straightforward and repeatable.
TIG Welded Steel Crossmember Supporting Modern Transmissions
The crossmember is fabricated from heavy gauge steel and reinforced with TIG welded seams at high stress points to resist flex under torque. It locates T56, 4L60E, and 4L80E transmissions at the correct height above the frame rails without requiring any tunnel modifications. A polyurethane transmission mount cushions sudden load shifts, reducing noise and harshness during acceleration. Precision machined bracket surfaces and spacers maintain consistent tail housing placement, preventing binding or misalignment of the driveshaft. This robust structure ensures long term durability even when paired with high output LS engines.
Enhanced Oil Pan Clearance Preserves Chassis Geometry
This kit raises the oil pan above the frame rails to maintain optimal ground clearance while preserving full suspension travel. It accommodates modern high clearance or cast aluminum sumps and fits neatly within the existing transmission tunnel contour. Engineers validated that exhaust routing remains free of interference and steering linkages operate without restriction under full lock. By avoiding any cutting or reshaping of the floor pan, the original structural integrity of the X Body chassis is retained. Enthusiasts benefit from modern oil containment design without compromising ride height or handling characteristics.
All Inclusive USA Built Kit Ensures Hassle Free Installation
Every bracket, spacer, and bolt needed to mount the engine and transmission is included in the hardware pack, eliminating extra trips to parts stores. Components are produced domestically under strict quality control, with CNC machined surfaces inspected for tight tolerances and welded assemblies tested for structural soundness. Detailed step by step instructions guide installers through each phase, from frame mount installation to final torque checks. Whether fitting a 4L60E or a T56, the kit delivers a consistent and repeatable outcome on every build. This comprehensive approach guarantees a smooth LS conversion process and lasting reliability on the road.
