The Adjustable LS Engine Mount Plate Set (#34-0302) allows installation of an LS series engine into a truck originally equipped with a small block Chevrolet V8. The engine mount plates are slotted to allow for 1-7/8" of adjustment in mounting position to provide for better weight distribution, additional clearance for engine driven accessories (allows for low mounted A/C compressor) and oil pan to crossmember clearance. Engine Mount Plates accept small block Chevrolet engine mounts, sold separately.
