Yup. They look just like them.  Very pricey though. That seems to be coming around again for me David? I feel a project coming on. I've got to go looking at CPU combinations. I don't like the manifold that Borla is offering for their set up as the linkage requirement on a Pantera is unique which is why the cast in linkage tower is on the Hall and Detomoso manifolds.

You need to mount the carbs/throttle bodies with the fuel inlets outboard so that you have reasonable throttle access running down the middle of the manifold.

On a Pantera it is hard enough to work on them to begin with and changing the access to the linkage could be the straw that breaks the camels back?

The original design considerations for the mounting on the Pantera are correct for the car but if you mount them on a different car like for instance a Mustang you want to reverse the entire linkage design and run the carbs in parallel and side mount the throttle. That is where sometimes the "experts" disagree.

I've run them both ways on both cars and perhaps the criticism against my advice is that others don't understand that I have a unique perspective on that subject?



You might find my next comment moot but I have found that there is a loss of power across the rpm scale if you mount the carbs in parallel. The reason is that you change the line of sight from the throttle plate opening to the valve.

Seems silly but the power change is very measurable.




There were several vendors that had the adapters for the side drafts listed. Hall had pictures of them installed on a Pantera. Probably the car that you are thinking of Boss?



You need to note though, that the point of the down drafts was that you were able to achieve the optimum distance to valve of 4.5 inches and direct line of sight to the intake valve. You can't do that with adapters or with the side drafts.

You can do that if you take the FI side draft intake manifold and rifle bore the throttles thorough the manifold mounting flanges. To this day I have not seen anyone do that.



I am not versed on the IDF's. The Cobra guys aren't either so I'd have to search for that chapter of expertise and am wondering if those "authors" are still with us?

I do know that they were on the earliest factory Cobra race cars with 260's. That's like one or two cars. Where they were "sourced from" I don't remember and I'd be relying on the accuracy of early magazine articles and hope that the author mentioned that and that I've just forgotten?
