Also- it would be interesting to have a story on building and breaking in a new engine- would you use synthetics? Is there a particular way to build an engine wherein synthetics would be useful as a first fill? How do the OEM's (Chevy, Porsche, BMW) ship their engines with synthetic new from factory? How long does it take to break in an engine? Does the "motoman" break it in like you drive it theory hold water?

Good story regardless.
