It's a little rainy today, in Montreal, so I'm getting a few things done. The original /6 heat exchangers I got from Jon Lowe were in pretty good condition, except that one had a hole in it.

So I brazed in a patch. I like brazing for this sort of work because it's easy and leaves a low profile patch.

Unfortunately, I left a couple of little gaps after the first go-around.

So I went over it again with the braze rod. Another advantage is that repairs are easy to make when I don't get it quite right the first time . . .

The result. This is as good as I can get it.

On the green car, I currently run headers, modified to provide heat to the MFI warm up regulator. The plan is to install the heat exchangers very soon so that I can have the exhaust I plan to use long term before the PMO carbs get the final dial-in.

I also plan to show the rest of the heat exchanger install in this thread.

See for the PMO chapter.

Back from the chrome shop. I simply had them dip the heat-exchangers and sand blast them. Quite a bit of pitting, and I found hole in the header itself. Nothing that can't be fixed quite easily.
