Average life expectancy of someone living in the U.S.A is 78 years if you make it the whole way. Doesn't have much to do with a mechanical engines life. I'm gonna go with lamonsters guesstimate of 100,000 miles.
What I was trying to show is that no one knows how long anything will last. If you take care of what you have, you give it a better chance of a longer life. I believe that the Spyder engine has a very good chance of getting 100,000 miles, but if one just trashed it out, it won't make 20,000. Care extends life...yours or your Spyder's.
