They say Hall Pantera on them.
If they are out of stock on them, then grab whatever you can, anywhere you can find it. I doubt they will cast up any more. That will make the prices of used ones just inch up.
Original GT40/Cobra intakes for a 289 can bring over $2,000 now. It isn't out of the question that a 351c could wind up like that also eventually.
Incidentally, there is a Detomaso logo IDA manifold for the 289/302. Ever see one? Care to speculate on how much it would sell for?
A manifold plumbed for vacuum is easily worth another $500 for that option. Don't believe me? Plumb one yourself and find out why?
If on the other hand, someone is talking about a Detomaso lettered 351 C manifold for IDAs, that is a horse of a different color.
No one knows for sure but it would seem the minimum amount of those were made. Edelbrock takes contracts for casting manifolds for other companies.
Minimum runs from them were in the day 100.
Don't know who cast the Detomaso version. Could have been them, but they are worth a premium price for sure. I have NEVER seen or heard of one coming up for sale publicly.
Buddy Barr did the majority of aluminum intake castings for Ford. Offenhauser did some also on the Cobra high risers. The Detomaso casting pictured here really doesn't have any of their eaearmarkings that I can notice. The part number cast in like that makes it look like a European casting if you ask me?
They were only made in the 4v version as far as I know AND the ONLY Cleveland version I've seen is the one that George posted in his sticky on intake manifolds. Nice find George!
Current prices from Hall are about as cheap as you can get. They are the source of these manifolds to companies like Inglese that are going to mark it up to $1,100.
The Hall manifold is going to be a better performing manifold than the Australian versions since it is a copy of the original from Detomaso.
None of the Australian manifold are made for 4v heads. They are made for 2v heads. Some can be adapted.
It has(the Hall or Detomaso) the runner height (runner length)that you need to generate good torque, and the line of sight to the intake valve. The runner length and size is essentially tuned to the 351 4v head.
This design, the Detomaso IDA version, is actually better than the 289 design since it has longer runners for better off idle torque.
It is said that the original design was done by Holman-Moody and that there is a Holman-Moody manifold version. Never even heard of its existence but I wouldn't be shocked if it's true. Many of the H-M manifold I saw were hand built and welded up and used as patterns. Sounds like this is the case with the Cleveland manifold that they built?
I was told by Gary Hall 1) he claimed he had an original Detomaso version, 2) it tended to be thin and fragile and crack easily 3) his is thicker. Seems to be mostly the carb mounting flanges that are thicker on the Hall.
Also on the Pantera you do not want to use a throttle bell crank mounted on the side over the valve cover. You want it in the center so that you don't have to make a new throttle cable , or more correctly, re-invent the throttle cable.
The Hall has the pedestal where it should be for a Pantera (just like this DeTomaso version). I am suspecting though that the Detomaso race team built a special bellcrank especially for this setup though. Hours of maneuvering with the manifold on the workbench to get the combination right makes me think that. Find a pic of that George.
This picture by George from the internet was a great find. It's the ONLY picture I've ever seen of the Detomaso manifold. Look at the part number cast into it! Very cool. I would sure love to have one. I am sure I couldn't afford it! PM me anyway if you have one. You never know. Miracles happen sometimes?
I'm wondering if since this one is painted black that it might have been cast in magnesium? I've seen that a lot on magnesium intakes to reduce the amount of corrosion they generate. Just makes me want this one more though. I have to learn to control my urges.
Look closely at the porosity of the casting under the black paint. That looks like typical magnesium pitting to me?
Look how thin the carb mounting flanges are. That is a concern.
I came across a letter from DeTomaso to me from 1978 where they answered my inquiry about a Weber manifold, IDA carbs and linkage to bolt onto the car. They quoted it in Italian Lire but the exchange cost in US dollars at the time came to $738. That was preassembled and pre-jetted? Wow. What was I thinking in not buying it? Probably was worried about the cost of the shipping? What a stupido?
