To Stroke or not to Stroke?

x2 on the "moon" comment...
Getting off of the discussion of only power level... I'd also like to understand if the horsepower is on a dyno, or as installed in a chassis (meaning chassis available headers, belt driven water pump, air cleaner, etc.)? Are we using a commonly available, street type ring pack and shelf parts aside from a camshaft? What are the expectations in terms of longevity and maintenance? What about overall cost to purchase? Are we simply ignoring all those factors?
