LT Engine Swap Mounting Plates Raw

The Billet Specialties LT Engine Swap Mounting Plates Raw are precision aluminum motor mounts designed for LS-based engine swaps into General Motors A-Body and G-Body vehicles from 1967–1972. These bolt-on mounting plates provide the structural foundation required to properly secure LT-series engine installations while maintaining factory-style durability and alignment. Available in raw aluminum finish, these plates deliver the mechanical reliability demanded by engine swap specialists and performance builders.

Constructed from aluminum for weight savings and corrosion resistance, the mounting plates measure 6.6 x 9.6 inches with a thickness of 0.8 inches, engineered to handle the mounting loads of a modern LS displacement while fitting the original mounting points of classic GM platforms. Raw aluminum finish allows builders to integrate these plates seamlessly into custom engine bay layouts without paint or coating complications. The kit format ensures all necessary plates and hardware arrive as a complete system, eliminating mismatched components or compatibility guesswork during installation.

This product is engineered for classic car enthusiasts and performance shops undertaking LT engine conversions on first and second-generation A-Body/G-Body platforms. Whether restoring a 1970 Chevelle SS, 1969 Nova, or equivalent Pontiac or Oldsmobile variant, these mounts provide the precision fitment and structural support necessary for long-term reliability. The bolt-on design eliminates welding, reducing installation time and preserving the originality of original mounting locations while accepting modern drivetrain architecture.

Billet Specialties specializes in precision-engineered engine swap components that maintain tight tolerances and clean aesthetics. The LT mounting plate system represents a purpose-built alternative to fabricated mounts, offering repeatable accuracy across multiple installations. Builders choosing this kit gain OEM-level engineering without custom fab work, delivering confidence in alignment and longevity.

Specifications listed below reflect the physical profile and material composition. Raw aluminum allows for custom finishing, powdercoating, or anodizing per builder preference. Part number 11630 ensures correct fitment and compatibility with other Billet Specialties LT swap components.
