Thanks you guys are a wealth of information. 

And still learning. ;)

This is going to be my next car one day

There is this on ebay: http://www.ebay.com.au/itm/Capri-V6-Triple-Intake-Manifold-/291581671982?hash=item43e39f3a2e
 
It is a modified production manifold - badly made, but a good attempt at some thing different.

3x350holley massive overkill still oval port and non ported by the looks.I'm thinking scrap value

I sold it to him years ago - it was off a speedway car (Nev Eltze - Hamilton way) -  Nev went from naturally aspirated (first carbs, then injection (u can see the facility on that manifold)  to a twin turbo set up so ditched the manifold. according to legend it produced 410hp with the turbos at (I forget exactly) 20 psi boost. It was stroked with chevy rods, chambered heads, s/s valves etc etc - a work of art (but kept breaking up)

For some reason most capris were swapped to Holley.  One of  mine had a 500 which was way too rich so I swapped down to 350, still way too rich.   Even the Holley book charts show they are too big.  Triple Webers are horrible to drive so triple Holleys would be far worse. Scrap value only IMHO.

Hi all, one of the cars I bought has an oval port twin carb setup with the carbs parallel on an oval port motor. Since then I've bought a Dport motor with single carb as well as this W pattern Dport manifold from South Africa. I do also have single port oval manifold. So obviously this triple manifold if for holleys would be ridiculous but which would be the best to choose. I know it depends on many aspects of the build but if it was the dream motor for thrill and cruising where would you lean? As this is the major power factor for these motors are there better options? or can we engineer an intake scenario better than has been done before. Here is a picture of the side of this manifold.

Spud, did you ever get around to converting that triple throttle body mechanical fuel injection to EFI?
