I have a pile of GMC engine parts (I hauled over 7 tons in two trips!) from a gentleman who spied my truck at a show and came over to talk to me about it. At any rate - among the piles of stuff, I came across these -

I fixtured them up to a 302 exhaust manifold (clamped and bolted as pictured) and the port spacing and size is identical.





The center dump piece is cracked and not worth fixing - but I was thinking that it wouldn't be that hard to fab up a piece to go between these two and use to mount a turbo . . .

Any thoughts?
