GM part # 12366573 SBC VORTEC INTAKE

[Grumpy]

I've got a GM Performance intake for a SBC w/Vortec heads. It is PN 12464340. It is for a 4bbl (not sure if square or spread bore).

I searched 2 pages on Yahoo, and the links either did not work, or didn't provide any info. I also didn't find anything on it on this site. I searched 3 GM websites...

Anybody know anything about it? I want to put it on a DD., either a 90 TBI Sub (it has the adapter and TBI on it now), or a '86 Sub w/a Qjet.
