Does anyone have a spare manifold for a V8? It doesn't have to be from an 8, any of the larger M60/M62 V8s use the same manifold (4.0, 4.4 and 4.6) so the E34, E32, E38, E39 and even X5 (ugh!) are all suitable donors.
The interesting thing is, I could buy a wrecked 740i for a few hundred pounds and grab the manifold from that, before selling all the other parts to recoup more than what I paid, but I don't have the space .
