Guy has a Ford tunnel port listed for use on a Pontiac RAM AIR V with gasket showing how close the Ford and Pontiac ports are.

Would be a lot of work to get the Ford intake to work on the Pontiac but the ports are close.

I know at least one guy who wants to use one of my intake adapters for a tunnel port, plus a Pontiac RamAir V intake manifold, for use on an FE. The ports are very, very close...

Have you set a 429/460 intake on one of the MR adapters to see how it fit? I think Joe Crain had mentioned that he had used a 429 intake on a PSE adapter before, but i didn't see any pictures.

I haven't, but the bore spacing on the 385 series is bigger than on the FE, so I would expect a mismatch. Kind of like the mismatch between the 351C intakes and the FE ports. The Pontiacs, on the other hand, have a bore spacing that is 4.62" compared to the FE's 4.63". Its a pretty good match...

The mismatch was not the problem with putting a 460 Victor on a PSE, it was the airflow. Why put a 550cfm manifold on a 320cfm head? Worse than the Dove spyder at anything below 6000rpm. It all comes back to having the manifold flow around 120-125% more than the head for a race engine that uses a cast intake. JMO, but plenum design, runner taper, and angle of entry into head are more important than maximum airflow. I would much rather have a smaller port continue to flow air faster at higher lifts and water pressure than one that flows a lot of air, but shears over the short turn and loses flow at any lift. If a port continues to increase airflow above 28" on my flow bench, I will sometimes check it all the way to 48" just to see if it will back-up or go turbulent. If it does, the shape is wrong somewhere. Takes a lot of patience to figure out what causes a port to go stagnant or back-up flow, and years of experience. What looks good does not necessarily work on the engine, or on the flow bench. JMO, but the more I learn, the less I make adamant statements. There are always exceptions to what is accepted as "gospel" from the past. Joe-JDC.

I was thinking about using something like this but mounting a modern blower on it. http://www.ebay.com/itm/Ford-460-CJ-Twin-Carb-Intake-Manifold-Satin-Optional-Blower-Mount-/181581856007?pt=Motors_Car_Truck_Parts_Accessories&hash=item2a471f3d07&vxp=mtr
