1986F150Six Posted May 2, 2018 Author Share Posted May 2, 2018 Worst case - run on the center carb. It is still basically the same manifold that you have now. Maybe Reamer could fabricate an aluminum box [plenum] with a removable top to mount on the lower portion of a F.I. intake manifold? https://tse2.mm.bing.net/th?id=OIP.xSVzVRFwiJw46jgaBCgVeQEsDg&pid=Api https://cimg5.ibsrv.net/gimg/www.ford-trucks.com-vbulletin/2000x1124/80-20141224_175359_611bc12fa949d63c38e3ab4de92e15208c5802c2.jpg The flat solid top piece could be modified for a 2 barrel, (2) 2 barrels or (2) 1 barrel carburetors!!!

Gary Lewis Posted May 2, 2018 Share Posted May 2, 2018 And another idea.... https://fordsix.com/download/file.php?id=2267&mode=view I'll let it go, now! I'm not authorized to see the last one. As for a box, those are problematic. Some work and some don't. I like the initial intake - 3 carbs. So, what carbs? Link to comment Share on other sites More sharing options...

So, what carbs? 3 of the stock older Holley 1940s worked very well in the past. They are a nice dual pontoon float design that was a service carb. for replacing the Autolite 1100. We used to put a setup on the old integral manifold Falcon/Comet in-lines, used 3 stock carbs, center was primary and ends were progressive.

Whisler Posted May 3, 2018 Share Posted May 3, 2018 3 of the stock older Holley 1940s worked very well in the past.

We used to put a setup on the old integral manifold Falcon/Comet in-lines, used 3 stock carbs, center was primary and ends were progressive. I used to have a Mercury Monarch (same as Ford Granada) with the 250 ci (4.2L) six cylinder engine and 4 on the floor trans. (3 + OD). I always wanted to cut the manifold off at the head and construct a tubing set-up to use 3 side draft Harley Davidson carbs similar to what my Austin Healey 3000 used (it had 2 SU side drafts). The 3 Harley carbs calculated to have the right flow for the 4.2L six. Just a dream in my case as I didn't have the fabrication skills. Link to comment Share on other sites More sharing options...
Ford F834 Posted May 3, 2018 Share Posted May 3, 2018 Check this out! It appears to be made using the center section from 3 pre-EGR intake manifolds. http://www.jalopyjournal.com/forum/attachments/1482-jpg.2772244/ With the phenolic spacer, the carburetor is clocked such that all 3 carbs can be connected in a more normal manner. [Heim joints?] What say ye, Jonathan? It looks to me like those are EGR manifolds with the hole filled in? Definitely has a flat lobe in that location next to the intake hole. This looks like a fun build but I am still working at getting ~one carburetor to work right, let alone three! We will see what happens after the diesel is running. I will probably start itching to warm up the straight six performance 😇 Link to comment Share on other sites More sharing options...
