Hmm, why is it always the infrequent members that get snappish when asking the occasional technical question?
Perhaps you and 929 had some initial misunderstanding, but he did indeed provide you valid advice (albeit not what you were looking for) as well as srv1 also answered your question. Its pretty much common knowledge (hence calling the question ridiculous) that despite how well a high mile engine runs, its not always a good idea to subject it to the added stress of forced induction. Of course, no 2 engines are alike and some are indeed stronger than others, but as a rule I think most people prefer to have a blower/turbo on a newer engine.
If you can do the installation yourself, heck why not slap the blower on the one engine, and start a project in the meantime? It will give you a chance to decide if unnaturally aspirated is the thing for you, or maybe you'd be happier with N20 or an all-motor combination. Only one way to find out
Good luck to yah!
