i need to do something about spare blocks, engines, trannies for various racecars, etc.

i could buy some racks but would like to make something if anyone has some ideas for something innovative. like taking a standard 4 wheel engine stand and modding it to have the tranny on the bottom (sort of under the engine). this would make the whole thing easy to wheel around.

or buying the wheeled dolly sets for $30 and making an adapter plate on the bottom to stand a motor or tranny to and being able to move around.

suggestions?
