Speedmaster PCE169.1018 GM LS Engine to 3-Bolt Chevy Motor Mount Adapter Plate Kit

The Speedmaster PCE169.1018 motor mount adapter plate kit is engineered to simplify LS engine swaps into vehicles originally equipped with traditional small block Chevrolet engines. This comprehensive adapter solution allows you to install modern GM LS-series engines using existing 1972 and earlier style steel frame stands with rubber isolator mounts.

Key Features:

• Converts 3-bolt Chevy rubber motor mounts to accept GM LS engines
• Compatible with 1972 and earlier steel frame stands with rubber isolators
• Positions bellhousing mounting flange approximately 1 inch forward for improved clearance
• Precision-engineered for proper engine alignment and fitment
• Durable steel construction for reliable long-term performance
• Complete kit includes necessary adapter plates for installation

Installation Notes: The forward positioning of the bellhousing flange provides additional clearance but may require modifications to the transmission crossmember and driveshaft length. This design ensures proper driveline alignment while accommodating the dimensional differences between traditional small block and LS engine architectures.

Ideal for hot rod builds, engine swaps, and resto-mod projects where you want to retain the original frame-mounted motor mount configuration while upgrading to modern LS power.
