MuscleRods LS Engine Swap Kit for 1970-1972 Chevy Monte Carlo
Swapping an LS powerplant into a 1970-1972 A-Body Monte Carlo often comes down to precise mounting and angle control, and this Engine Swap Kit delivers both with tailored engine mounts, frame brackets and a transmission crossmember built to support 4L60E or 4L80E setups. By preserving the correct drivetrain angle the kit eliminates vibration and reduces stress on universal joints while accommodating high clearance oil pans without modification. MuscleRods engineered each steel component in the USA to match GM A-Body frame rails and ensure a reliable fit for any Monte Carlo restomod.
Maintaining Optimal Angle for Smooth Power Transfer
The conversion kit holds the LS engine and automatic transmission at the ideal tilt to preserve drivetrain angle on the A Body frame. By aligning the crankshaft and torque converter within the correct plane, the design reduces vibration at the universal joints and relieves stress on the driveline. This approach also clears aftermarket oil pans by offering ample space above the subframe rails. The result is a more refined driving experience with minimal noise and prolonged component life.
Rugged Steel Mounts with TIG Welded Reinforcements
Each mount and bracket is cut from high grade steel plate and finished with precise TIG welds at key junctions. This method delivers superior rigidity where engine torque tries to flex the frame rails. All components are produced in the United States and undergo inspection to ensure consistent fit and weld quality. Motorists can have confidence that these mounts will resist deformation even under spirited acceleration.
All In One Solution for A Body Monte Carlo Restorations
Rather than gathering parts from multiple sources, this kit unites motor mounts, frame brackets, a crossmember, and a vibration damping transmission mount in a single package. Included hardware is tailored for both 4L60E and 4L80E transmissions so no additional tunneling or fabrication is needed. By matching every bracket to the factory frame rail profile of model years 1970 through 1972, install time is cut dramatically while fitment remains precise.
Versatile Transmission Support Boosts Installation Flexibility
The integrated crossmember and polyurethane transmission mount accommodate both common GM automatics without tunnel modification. Specially spaced mounting points adapt to the dimensions of 4L60E and 4L80E gearboxes while maintaining the correct drive angle. The soft vibration element within the mount isolates engine shake, enhancing comfort for daily use without compromising drivetrain rigidity.
