Newbie here with manifold question

[4regt4]

An older GM performance catalog showed a intake manifold for the iron head series motors that held 3 Weber IDA 2 barrel carbs. It seems that it bolted onto the base of the factory FI manifold. (The factory manifold for my 3.4L is two piece.) Anybody know anything about this manifold? Or any other way to adapt an individual runner type setup for triple deuces?

I'm building a Stalker V6 kit car, which uses the rear drive varient of the 60deg V6. Runs like a rocket with the 2.8L motor, really impressive with a warmed up 3.4L. Only 1300 lbs.

That is a fabricated manifold. Not an over the shelf GM part.

Not true. It's not a GM part, but "Manifold tops are available from aftermarket sources to mount triple Weber carburetors on a tuned port fuel injection manifold base." Direct quote from an older GM Power Catalog.
