Designed to ship engines by air or road. The Chev/Ford mounting system utilizes two moulded plastic mounts (sold separately) that bolt directly to the motor mount pads on the side of the block. The engine is then lowered into the bottom half of the container. The back of the block bolts directly to the container using four of the bell housing mounting bolt holes located just above and below the dowel pins. Bolt the top half of the container in place and you are ready to ship or store your engine.
