Roger Lister's Mitsubishi 3.0 Liter V-6 Engine Specifications

Roger Lister wrote:

I'm pulling info from many sources.  Dr. David Zatz and his ALLPAR site, my friend Rob Carter's 3.0 FAQ and his General FAQ, Gary Donovan's site, Paul Berkebile's site, James Dempsey and his Chrysler 3 liter mailing list, Rob Carter and I collaborated on the NEW Mopar minivan Homeworld, and my own personal research [Webmaster note: dead links have been removed].  And many other sources and people and such.  Too numerous to mention.  Including several Chrysler service techs who shall remain nameless for their own protection...
