Flowtech LS engine swap motor mount adapters are designed to ease the task of swapping an LS engine into vehicles that were originally equipped with Small or Big Block Chevy engines. With two different mount adapter kits available, you are sure to find the mounts needed to position the engine and transmission assembly in the appropriate location. The Flowtech adapters are slotted for clearance of polyurethane motor mounts that would otherwise protrude into the adapters.
