storing spare engines

I have a 2 bay garage and have to house my Imperial, My duster and 3 engines. I built this out of sleepers and 4 x4 for legs. Its all braced at the bottom between the legs and the blocks holding the engines are notched into the base of the rack. I have room underneath to store a couple of transmissions. I also have a 360 on engine stand right hand side beside rack which im building up to a 408. The engines are off the ground and out of the way which I find great.
