MuscleRods LT Engine Swap Kit for 1968-1972 Chevelle A-Body
If you are fitting a Gen V LT engine into a 1968 to 1972 Chevelle A Body this 1968 to 1972 A Body LT Conversion Kit delivers precision CNC machined engine mounts and custom steel brackets that bolt directly to stock frame rails to align and preserve chassis geometry. By replicating factory mounting points installers avoid shimming and maintain driveline angles that yield smoother power delivery and reduced vibration while the crossmember and transmission mount support 4L60E and 4L80E without tunnel trimming. Built in the USA by MuscleRods this bolt in package includes a low profile oil pan design to guarantee hood clearance under the stock bonnet and cuts installation time so focus stays on driving rather than fabrication.
Precision CNC Engine Mount Geometry
The conversion kit's engine mounts are CNC machined to mirror the exact contour of the 1968 to 1972 Chevelle A body frame rails, achieving tolerances measured in thousandths of an inch. This precise fit removes the need for trial shimming and ensures driveline angles remain true to factory specifications, yielding smoother power delivery and noticeably reduced vibration at highway speeds. Installers benefit from a straightforward drop-in process that slashes swap time by eliminating guesswork, while preserving original under-hood layouts for easier accessory alignment and routine maintenance.
Custom Steel Frame Bracket Reinforcement
Fabricated from heavy gauge steel, the custom brackets anchor directly to stock mounting points and spread engine and transmission loads evenly across the chassis. By maintaining original suspension geometry, these brackets resist stress concentration that can lead to metal fatigue or frame distortion under high torque. As a result, handling remains crisp and consistent, and ride height stays true even when unleashing modern LT power. The robust design also safeguards chassis integrity for decades of driving enjoyment without welding or permanent modification.
Simplified Crossmember and Transmission Support
The included crossmember and transmission mount accept both the 4L60E and 4L80E without any tunnel trimming, thanks to precision placement and strategic reinforcement. Every bolt, spacer, and fastener needed for installation ships with the kit, allowing builders to secure the powertrain immediately upon delivery. This direct-fit solution not only preserves the original floorpan strength but also improves underbody access for oil changes, filter service, and performance upgrades. Future rebuild or swap tasks remain efficient and cost effective, minimizing downtime.
Gen V LT Engine Fitment and Low-Profile Clearance
Engineered for compatibility with Gen V LT platforms such as LT1, LT4, L83, and L86, this kit pairs seamlessly with a cast aluminum oil pan solution to clear the stock bonnet height. The low-profile pan design prevents contact with the firewall and hood frame, avoiding cutting or reshaping factory sheetmetal. Builders retain the Chevelle's classic silhouette while benefiting from modern power and reliability. By combining accurate fitment with thoughtful clearance allowances, this package unlocks contemporary performance in a vintage chassis with minimal modification.
