I plan on running 8 stack E.F.I. on my car and I'm looking for opinions on what is the current state of the art available today. Holley seems like the way to go for ECU but I'm not sure who makes the best Manifold and throttle bodies. I'm looking at Borla, Inglese, and Hillborn but are there others I should consider? Do any of these companies cast their own manifolds...if not then who does? How do you determine throttle body size? The engine is a 408 cleveland with iron 4v heads, it made 500 H.P. on the dyno with a 750 Holley on an Edelbrock manifold. I also intend to run 180 headers if that matters.

Thanks, Randy

Original Post

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.

borla

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 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. 

http://www.wilsonmanifolds.net...egory&path=79_93

I couldn't see anything there that's suitable for an 8 stack EFI intake. 

Ok, my bad. I was thinking through this stupid cold!!

Randy, 

For your consideration, attached is a picture of a "cross-ram" EFI IR intake that Lance Nist brought to a recent Pantera Club meeting here in So Cal.

Lance also has his own line of "Pantera EFI" ECUs.

Cross Ram Intake

Haven't seen many of these intakes on Panteras, but could be an option to have both longer runners *and* visibility out the rear. (Although may not fit w/180 deg headers.)

Is this the Borla/Kaase 351W intake or the infamous Australian intake? Have you actually seen one on a Pantera? 

The "infamous Australian intake" you're referring to is, I presume, the system from Morrison. I spoke w/them and have seen their intakes at various trade-shows over the years. And from what I recall, their intake used shorter runners.

So maybe this is the "Borla/Kaase" intake. Lance Nist would know for sure. Reachable via www.panteraefi.com

I recall seeing at least one Pantera with the Morrison intake. Looks like a great way to potentially fit everything under the standard engine cover.

I tried to buy a Morrison intake years ago but discovered they are made-to-order. The lead time is at least 1 year. Maybe things are different now. 

I think the Borla/Kaase manifold could be made to work but it would likely require modifications or specific cylinder heads. 

Keep in mind, a “stack” intake can be made to fit below the deck lid by the careful selection of components. 

 

David, 

At least a year!?! That would certainly help explain why I haven't seen more of these on other Panteras!

Certainly you could fit upright "stacks" under the standard engine cover, and I've seen some great examples on this forum where that's been done. May be easiest for a race' application where the shorter runner length is tuned towards higher rpms ... and where the engine can be lowered.

I just did a search on this forum under "IR EFI" and found a bunch of examples of low profile set-ups, including a thread on the Morrison intake. Forgot what a great repository of info this forum provides!! (Thanks George!)

Dave

As an update...I spoke to Borla yesterday and their intake with the built in vacuum plenum is not ready for primetime yet. They were very vague when asked when it might be ready and about any details as to where they were being made. I also spoke to Jim Inglese and he relies on Borla for a lot of his parts (the manifold pictured on his website appears to be the same one that is on Borla's website. It's seams both companies are being very misleading about advertising a working system that isn't really available...very frustrating.

If interested in more details on fitment issues, some great info from Kelly Coffield's work on EFI as shared by Dan Jones here:  https://pantera.infopop.cc/topic/351c-crossram-efi

I have one of Kelly's intakes and it's well designed but it's made for a 9.5" tall block and C302B or Brodix heads. He also had a version for 9.2" blocks with the same heads. Kelly's throttle bodies are "low profile" so the system, with air cleaners, will all fit below the rear deck lid. I made some modifications to mine, to lift the TB's about 3" and aim the injectors at the intake valve. This gives me an effectively longer runner but still (barely) fits below the deck lid. I'm using a Holley Dominator ECU and Jenvey drive-by-wire.  

IR Intake

Not only did Morrison tell me it would take a year or more (possibly much more) to manufacture an intake for me, they wanted 50% up front...non-refundable! I suggested putting funds in trust or a "ship-by or provide a refund" deadline but they would have none of it!  

It seems to me, for a 351C, the only readily available IR intake manifold is Hall's. Hilborn and Kinsler have intake systems with the manifold and throttle bodies integrated. They are both great companies and their stuff is awesome but their markets are more race than street. That being said, I seem to see lots of their stuff on street cars; mostly high end hot rods. If you don't mind going overseas, there are the Redline and Aussie Speed manifolds but I'm not sure of availability.

David, your system is just beautiful. If I understand this is a "one off" manifold? I came across another manifold from a company in Australia called EFI Hardware. It also has a built in plenum. What are everyone's thoughts on this one?

My intake manifold was manufactured by Kelly Coffield. He and I were in the same boat: 9.5" tall block and C302B (Brodix BF300 in Kelly's case) heads but no IR manifold for our combination. Lucky for me, Kelly decided to cast his own manifold. He did one run but last time I spoke with him, he wasn't planning to do any more. 

That EFI Hardware manifold looks great but do they really have them on the shelf? Also, don't make a cast-in MAP plenum your primary criteria. There's room in a 351C to hide a plenum below an IR manifold such as Hall's.    

The "EFI Hardware" manifold looks like an identical casting to the manifold in the Borla picture.

You don't need the vacuum box.

There are 8 port "distribution blocks" on the market that are perfect for the PCV plumbing … or MAP sensor . Tack it to the bottom of the manifold, plumb it to all 8 runners from underneath, and one connection for the PCV valve or sensor. The whole assembly is out of view. This one is Edelbrock #76578.

edelbrock

Another neat trick for individual runner induction is a separate electric powered vacuum supply for the brake booster. It eliminates the power brake vacuum plumbing as an eyesore or a plumbing issue.  Providing vacuum to the booster this way is common these days for electric cars, turbo & super charger applications, customs, and drag racing. 

A few OEMs have small, quiet, electric vacuum pumps. Add a small tank for volume & a vacuum switch to turn the pump on & off. I think there are some all-in-one units too; as I remember Audi has one that is popular.

Mount this vacuum "assembly" below the car, immediately under the brake booster. All that is needed is a 12 volt wire for power, and a short vacuum hose to the booster.

George, with the advent of electric cars, vacuum pumps that are designed to supply power brake boosters are common. As they are designed for a power brake booster application, they are usually a self contained unit with the appropriate pressure switches. I use one of these OEM vacuum pumps and stealthily hid it behind the driver's side headlamp.  Hella makes a good one, which I believe is the same as the Audi pump. Summit has them in stock!
