I'm with Glenn--I sure wouldn't be in a big hurry putting an engine together now! It is nice to have the engine (or one just like it) disassembled and cleaned during the build process as there are so many things that need to be done with an engine installed. Never could see any good reason to have a "done" engine sitting in the car and getting all filthy dirty and dusty during the build of the rest of the car, also could never see a reason to have a "done" engine hanging on a stand for the duration of the rest of the build, just too many ways for things to go wrong!!!!!
