I don't know the dimensions off hand but I do know they will fit in the back of a 740 wagon standing upright. The difficult part though is getting it in there with an engine hoist since the hoist will want to hit the top of the hatch opening. I had to use a piece of pipe as a crossbar and very short sections of chain to lift the engine, rather than one longer piece of chain, as that added too much height.
Or if you're buying it from a place that can load it in with a forklift, you will have no problems, just have to work carefully pulling it back out.
