I've had this under-carb tray on since the early 70s. It's a pretty good insulator from the header and there are no interference problems.

PS: I took a snap of it, but can't get the paper-clip thingy to work.

A-ha! Technology can't get best of this old Okie!

Here is the snap.

So I spoke wioth my "GUY " today about the part, He said "that would be breeze, do you mind welded corners?" He wants me to take some measurements of the bolt patterns and figure a width and length and he said he'll build the first one for about $100 but after he sets up the computer jig, the rest would be about $50 each.

My rough estimate on the size is 22" X 6" X 1/8" thick Aluminum Allow with about a 3 degree slant? That's off the top of my head.

I just need to make sure that the material and gas (back and forth) and shipping is taken care of. SO if you have a Cannon Manifold with 40, 44, 50mm Webers, and you want one of these for your triple WEber set-up, I'll be taken pre-orders as of right now!

email me at wolfin32z@yahoo.com We'll go with the $80 plus $10 shipping for each one. But I need at least 5 paid orders for him to make a batch. Let me know what ya think. 1/2 price ain't bad, I know I'll be buying one, Especially before the MSA event.

I believe what's important also is the finish of the plate.

The best finish for our application would be chrome on the exhaust side to reflect rays and heat and black on the carbs side to absorb heat.

I would take one

I'll set you the money as soon as there's enough people on the waiting list if you don't mind

Stainless would be a better material, as it doesn't conduct heat very well. It's more expensive as a raw material and harder to weld so it may drive the price up a bit. I don't think this shield needs to be nearly 1/8" thick either. You could probably use 22 gauge sheet.

[Zs-ondabrain]

I say 1/8" cause it's very strong and less likely to jiggle under vibration. Someone else mentioned chattering of the plate on the headers or carbs but I looked at my ste-up and there is PLENTY of room between the 2 of them.

Stainless would be great but obviously more expensive. I'm thinking that the raw finish is nice enough, but being Aluminum, it can be polished to a nice luster to reflect the heat on the bottom side. Not to sure about the whole "Black on top" though. I, like most, like the shiny stuff under the hood. If it were painted of powder coated, would gas from the carbs ruin or take that finish off?

If any of you are serious about getting one of these, Email me as mentioned above. I'll start a folder and when I have 5 orders, I'll email those 5 peolple witrh payment arrangements.

Making it thicker is one way to make the part stiffer. Another would be incorporating a lip on the edge, like the piece you're competing with. A third would be to roll beads in the sheet, like a floorpan. What you have planned should work just fine, by the way, and I'm not trying to be a PITA...

[Zs-ondabrain]

I just like the strength of 1/8" and it will have the folded edges like the competitor peice. Either rolled edges or folded and welded edges.

I did the manifold change to the mikuni short intake style. The heat shield fits great with the Datsun comp header which has longer runner (see the photo) than most other headers. I did a fit with the SU set up and this header, and the bottom of the carbs hit, thats how far the tubes come out. Any way this style heat shield will fit even the most difficult setup.

[fixitman]

Perhaps these photos will provide a few ideas for a heat shield as well as a balance tube. Note that the original fuel rail brackets have been used for fuel supply, fuel return, vacuum and fuel vapor purge.

I just use a flat piece of .090 aluminum that I got at work. The Webers have a threaded hole in the bottom that I put a threaded stud in and just mount the plate between two nuts. No vibration and real easy to get off to clean or polish.
