Good Call on that web link Bandit! That's the one I remember pouring over for couple of hours a couple of years ago. There's also a cool SD-455 engine article in a 73/74 issue of HP Cars magazine (If I remember correctly, the one w/ the "cartoon'y" reddish 73 GTO on the cover).
As for the 'Intern' thing, I think I could talk my advisor in the AET (Automotive Engineering Tech) dept. to allow me to get credit for it..sure beats the hell out of beta testing diagnostic scan tool software for OTC here in MN.
