I think most of that stuff is just sitting there. Some may or may not fit the engine where it sits. As I recall, there are 3 440's, one 413, one 400, at least one 360, maybe a 383 or two, and a couple 318's. I couldn't keep track of it all in my head. There is also another row of engines with a hemi in it. I will post that pic below.
That D800 dumper is still available for ONE K! Air brakes, 361, extra eqpt axles! (factory)
