One of the posts on this video is that it has a Vette motor in it. http://www.youtube.com/watch?v=ZPRH_fV3VP0
That's what I thought too. I remember a thread on here about his build too. I'd like to confirm so I could inform that dude on the youtube thread that it ain't no Vette motor. LOL
Yes that's Paul's wagon, I've known him for years, one of the nicest guys you'll ever meet, and yes it is 100% Buick powered.
