All the fuel induction stuff: MAF, TB, UIM, LIM, fuel rail (with injectors and FPR). You can sell the 19# injectors, rail, and FPR as an upgrade (I think earlier Duratech FPR's ran a lower pressure). Heads with cams (those SVT cams are much lusted after). Exhaust manifolds - great for gutting when off the car!
Of course, this assumes you want to go completely nuts and bother to sell all this stuff. It also assumes the yard will let you part the motor itself - not many do, with the early death of many SVT motors they fetch a pretty penny from reman companies. The intake stuff forward of the UIM (or TB) shouldn't be a problem though (i.e. TB, MAF, airbox, depending where they draw the line where the "engine" begins).
I just realized that I might want the oil pan (depending on whether my leak is a gasket, loose bolts, or the pan is damaged). Hopefully I'll be able to find out this weekend and might have to take a trip to your junkyard. No need to grab that on a "maybe".
