Do you want to swap an LS engine into your vehicle that originally had a small block Chevy engine? If so, you will need our small block Chevy to LS adapter plates. These plates are designed to bolt your existing 3-bolt motor mounts to the 4-bolt pattern of the LS block. They are made of billet aluminum and CNC machined for a precise fit. They also have a cutout to clear the hump on the backside of your motor mounts, so no grinding is necessary. Our adapter plates come with all the hardware and instructions you need for an easy installation. They are compatible with any LS engine and any small block Chevy vehicle, such as Camaro, Nova, Chevelle, Impala, and more. Order yours today and enjoy the power and performance of an LS swap.
