Hooker BlackHeart 71221019HKR Heavy Duty Gen V LT Clamshell Engine Mount Kit

The Hooker BlackHeart 71221019HKR Heavy Duty Clamshell Engine Mount is engineered specifically for Gen V LT engine swaps into 4th Gen F-Body vehicles. This robust mounting solution eliminates the rivet drilling required with OE mounts while providing superior strength and durability for your engine swap project.

Key Features:

• Heavy duty 11 gauge steel construction with reinforcement ribs for maximum strength
• Two-piece bolt-together clamshell design eliminates rivet drilling
• Durable powder coated finish for corrosion resistance
• Designed for use with Hooker BlackHeart LS/LT Polyurethane Inserts (P/N 71221016HKR Black or 71221017HKR Red, sold separately)
• Positions engine crank centerline and transmission mounting plane identical to stock LS engine location
• Compatible with all Holley LS swap kits utilizing 4th Gen F-Body mounts
• Hardware kit included for complete installation

Application Notes:

This mount enables installation of Gen 5 LT engines into vehicles already equipped with Holley LS swap kits while maintaining the same transmission position and crossmember. Each mount consists of one upper and one lower plate and is sold individually—two mounts are required per vehicle. Note that new headers will be required when converting from LS to LT engines.

Ideal for performance enthusiasts upgrading to the modern Gen V LT platform while preserving their existing LS swap transmission setup and drivetrain geometry.
