This aluminum mounting plate is designed for LS engine swaps into vehicles originally equipped with Small Block Chevy (SBC) engine mounts.

CNC machined from aluminum, the adapter plates feature four mounting positions, allowing adjustment of the LS engine location while retaining the existing chassis-side mounts.

The plates move the crankshaft centerline approximately 0.17 inches upward. A center relief opening provides clearance for raised features on the back of certain SBC/BBC engine mount brackets.
