is anyone here familiar with it?

 

not familiar, but a perfect component to use with RBob's ebl. better than trying to build a dual 4bbl manifold with adapters. just think the ability to use 4 90 pounders. would look real good on a 632 i found.

 

lets be honest here, the only aesthetically proper way to fuel a 632 with tbi would be a custom sheetmetal intake that has individual runners with 8 bored out 53mm single tbi's from a crossfire intake.

 

Looks homemade, those are GM injector pods and holley's 4-barrell setup had the "tower" coming out of the middle of the base plate. Those are huge throttle plates as well, looks to over 2".

 

I tend to agree - it looks like a Holley square base from a carb, with oval adapter plate to mount two injector pods back to back. Note, no IAC to be found. This thing should be fun to make it idle. Also, how about TPS? TPS can be driven separately of the throttle lever via adapter cable.

That has to be custom. It looks like a standard base with a custom made top plate... I'm thinking horrible air flow because of the dual pod towers... still quite unique though...
