Heh, get this. The father of a friend of mine happens to be a heavy duty mechanic. A few years back, when I told him I wanted a 400 sbc, he swore up and down that there was no such thing. I couldn't believe my ears, so I just went and got one, showed him, and let his face turn red as a tomato. On a similar note, anyone ever read the article in Hot Rod magazine a few years back where a "GM certified technician" asked HRM how to convert his Pontiac Fiero to RWD? All HR had to say was "um, all fiero's are RWD. GM Certified Technician eh?"... I laughed aloud.
