Seeking advice regarding component selection for an 8 stack E.F.I. induction

Randy, “state of the art” has more to do with controls and ignition than it does with hard parts. As always, the big question will be which manifold to use. I believe there are two readily available Weber manifolds: the Hall Pantera IDA manifold and Australian IDF manifold. Most throttle bodies have an IDA flange but I’m pretty sure they’re available for the IDF manifold from Jenvey in the UK. Once you’ve decided on a manifold, the rest becomes a matter of selecting parts and an ECU. Holley is an excellent choice. 

Thanks David, I thought I heard somewhere that the Borla manifold is a copy of the Hall manifold but has a built in vacuum plenum. Does that sound right? From their website:

"Cast in A356 alloy and machined in precision CNC equipment the manifold has cast-in plenum facilities for the MAP sensor and the Idle Air Control"

Are the Hall manifolds still being produced or are they selling old stock? The pictures on the Borla website and the Inglese website look to be the same manifold. 

A picture is worth a 1000 words.

Redline of Australia is the original manufacturer of the IR manifold with the built-in vacuum box. Its a 2V manifold with enough "flange" around the runners to seal-up around the ports of a 4V head. It uses intermediate adapters allowing it to be configured for either IDA or IDF bolt patterns. For that reason, its a tall manifold.

The Borla manifold below has a similar box, but its not the same manifold.  I'd guess they've designed their own manifold. You can see a corner of the box which has been added in the middle of the valley.

Below is the Aussie Speed of Australia IDF manifold, which like the Redline manifold is a 2V manifold  with enough "flange" around the runners to seal-up around the ports of a 4V head.

Below is the Hall manifold being used for IR fuel injection.

Below is the Hilborn "3 piece" EFI manifold for small block Fords. It provides manifold and throttle bodies all-in-one. Each bank of throttle bodies has a one piece shaft for the butterflies. Only linkage is that connecting one bank to the other. This gets my vote.

I found Jim Inglese to be friendly and knowledgeable. 

I talked to Hilborn about their system. Turns out Ken Lingenfelter has a Pantera now, and has had a Hilborn 8 stack system installed using a Holley ECU.

That's a nice looking setup, are all those hardlines connecting vacuum? 

Those hard lines are likely all connected to a common plenum for the MAP sensor. Something else to keep in mind; some EFI experts feel the injectors should be aimed directly at the base of the intake valves, if possible.

"Speed Costs Money....  How fast do you want to go, and how cool do you want to look doing it?"

Very nice!

Suggestion

My advice is to choose a system that enables individual balance when synchronizing the throttle bodies.

Not much point in trying to build one of these cars on a budget..."Ya gotta pay to play"

What would you look for to distinguish between one that does vs one that doesn't?

Hilborn quoted me a price somewhere around $12,000.

I think Anders is suggesting using 8 single barrel throttle bodies as opposed to 4 dual barrel units. 

I´have TWM on a Hall Weber intake on my motor. Them you can balance each bore. A little trickey but it will work.

A drawback for those system that have only one throttle axel.

Anders

FYI: TWM is now Borla Induction.

I have not seen any Borla/Twm throttle bodies that are individual, they all seem to be paired.

I don't think they do. The only source I know of, for a high quality single TB, is Jenvey in the UK (https://store.jenvey.co.uk/thr...s/sf-individual-body). Frankly, I don't see the benefit for a V8 application. 

how does $7,635.00 turn into $12k?

i'd just buy the intake & throttle bodies and use the new Holley Terminator X controller
