I'm not a big fan of the Powerstroke series, and I need a new full size van. The RAM vans aren't in production anymore (Though I don't think Dodge ever gave those diesels), and the Dodge/Freightliner Sprinter 3500's have a puny Mercedes 2.7L diesel. Chevy/GMC don't offer diesels at all. So, what's left? If I pulled an old Econoline off auction or out of a scrapyard or somthing and dropped out the engine, could I realistically drop in a real man's diesel?
