The pic in post #48 is a DBW engine and also has the bigger case alternator that the Tahoe does not. Right on the front (upper left of where the intake hose goes on) of the throttle body is a small circle with a number in it, what does it say? My guess is it's going to be a '03-04 flexfuel engine since it has the return style fuel rail.

Not to second guess you ls1nova, but wouldn't a flex fuel engine have a stainless steel fuel rail?
