I wouldn't be as afraid of the engine being as its from an known engine builder as I would if it was "joe racer", but I would rather put that money into building an engine myself. Thats just me, but engines that I don't see going together or have my hands on worry me. You just hear too many horror stories. I understand that is not an option for some, but even if I ordered an engine I think I would want to at least be involved in the setup.
