That manifold is made to fit the small Ford Six'es (144, 170, 200, or 250's) it won't fit the Ford 240 or 300 big six'es. Good luck :thumbup: :nod:

If you want something similar you can make a 3 x 1 intake from three stock intakes, using the two center runners from each intake. Go to http://www.inliners.org and look under tech tips for a photo essay.

I have seen this before in another thread and would love to make a setup like this some day. This will clear the efi exhaust manifolds? What does the throttle linkage look like? Any tips to assist in set up? (idle, choke, synchronizing....) Does the plumbing for coolant on the underside make this something that could be run in cool or cold climates?

I haven't tried it with EFI exhausts - I assume it would work.

I use an intermediate shaft that has three bell cranks to open all three carbs simultaneously. It can be activated by the stock cable with a bracket rework.

Find three intakes with the same carb stud spacing. There are two - 2 11/16 or 2 15/16. Or file carb bases to fit.
A special extended manifold lug clamp will be needed for the front carb as not all mounting lugs have identical locations. Painted orange in the pics.

One center choke should be sufficient.

You could plumb all three heat boxes for coolant heating if desired. Or not.
