With all the talk about heatshields on here lately I figured I would post a couple of pictures of the one off my truck. This very unflattering piece of fiberboard/asbestos/godknowswhatelse sat under the carb of my 82 D-150 for over 24 years. I removed it when I was rebuilding the carb since it had accumulated lots of crud underneath it and was falling apart.

I really can't comment on it's effectiveness since this truck has always had a hot start problem. This is even with the fuel line routed over the valve cover from the factory. Funny thing is, I had problems with hot starts when I had a 1945 on my Duster, but once I switched to a BBD the problems went away.

How do I know it's factory? The fact that it has a rectangular slot cut so you can insert a wrench and remove the EGR valve without pulling the carb is a good tipoff. It also has holes cut for the all the assorted linkages, brackets, cables and whatnots.

A fine piece of engineering!

Give 'em a break on the material; I'm sure they did asbestos they could.

Hey, do us all a favor, will you? Put that shield on a big piece of sturdy white paper and trace it accurately, then use a ruler to measure at least two dimensions 90° to each other and mark them on the drawing, then scan it in. That way anyone can get the file and print it out as a stencil to make his own new shield. I'll be happy to host the file(s) for permanent downloadability. Maybe do the trace/scan twice, once with the two shield halves assembled and once with them apart?

X2. I am sure someone could rustle up a CNC machine and make a run of those heat shields on aluminum. Of course, a two barrel heat shield would be nice too.

I once owned an 81 LeBaron coupe that had that heat shield. I wish I had either traced or kept the heat shield.

Was this installed above or below the carb gasket?

I believe it was installed below a thick carb gasket but above a thin one. I may be wrong since it has been over ten years since I owned that car.

That would make sence.

Mine was installed below the main the carb gasket on top of a thin gasket.

The idea of using an aluminum I have found to work well.
1. Is aluminum is reflective and helps keep the number one runner warmer for better atomization. Before using the deflector the #1 plug all ways ran a tad dark compared to the others.
2. The aluminum acts like a heat sync. With the fan blowing on it, it will cool down the carb by wicking away heat. I use electric fans which rarely come on unless I get caught in traffic. After shut off, the fans will eventually kick on which reduces heat soak to a minimum. Restarts are immediate, with no extra cranking. I use two of the thicker gaskets, one above and on below the aluminum sheet stock.

Bump. Did we ever get that trace? I've been trying to be patient I just don't want it to get forgotten

No I never did trace it. I've been too busy with other stuff (I.E. trying to keep my truck running)

I'll tell you what, since you actually need it, I'll go out right now and trace it.

I could possibly modify this one barrel into a two barrel.

Josh P, you have a PM

Since my scanner doesn't want to work, I'm shipping the posterboard copy of the heat shield to Josh P. After he gets it hopefully he can scan/upload it.

Jeb, see reply and thanks again!

I'll post the scan as soon as it comes in.

Josh, did you scan it?
I'd like to make one for my slant and may have access to a CNC machine soon
