Fabricate Dual Intake Manifold

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I am in process designing and building a dual carb manifold for the L143.

It will be constructed using CNC flanges and 1-1/2" mandrel bends.
It is designed to work with the F-head exhaust manifold (manifold will need to be slightly modified to share a flange bold on one side of the block flange). This will seal better than an single hole flange.
The carb flange is designed to mate to the Carter W-O. Although I could have the flanges cut with no bolt holes.
It will have a cross-over tube to balance pressure.
The assembly will be professionally welded.

I have 3D printed prototype flanges already. I need to get them cut and am trying to spread the cost across multiple sets.
Construction will be mild steel.
I am trying to decide how many flange sets to have CNC milled.

Would anyone be interested in buying a built manifold? Just flanges?
I am thinking it would be $300-350 for a built unit.

This is not a commitment to buy, but I am gaging interest. I need to put out some cash and want to serve the enthusiast community and get a small multi-piece discount.

	I'd be curious to see one of these. I've been toying with this idea for a while.

	I would possibly be interested. I can’t wait to hear more and possibly see photos.

	Here is the direct link. He used a pair of YF carburetors. He also tried this on his other 3A with a pair of WOs, but he never showed us that setup. He is quite a clever young gentleman. http://www.cj3apage.com/cgi-bin/3Ayabb26/YaBB.pl?num=1362362501/all

	He went on to say that he finally gave up on the WO setup.....didn't ever get it right but that he loved the YF setup.

	athawk11, thanks for the repost. I am basically doing the same thing, but want to have CNC flanges. I'm curious how the cross-over was designed - I'll connect with garage gnome. no fender, TateC - sounds like I need to fab some up before there is more interest - fair enough. I have to decide if I get some CNC milled to make a few - or just a 1-off set for me. thx for the interest.

	Curious why not going with aluminum? I am currently working on a cast aluminum intake that will mount a Weber DGV. I have it done except for TIG welding the two halves together (its split in the Plenum to add a spacer) Its designed to use a Weber DGV 32/36 progressive 2bbl. If I ever get it to my welder friend I can have it done in a week.
