Does anyone know a source for backdate heat tubes for 3.2?
I'm looking for something like this one, but only for a 3.2....
http://vintagebus.com/rstube/ Anyone know of a source? It's for my '84.

Ed, are you keeping the single stock 3" duct in front of the dist. that goes to the crossover under the engine tin? If so I modified a stock shroud piece to make the turn and go down instead of to the blower. I have B&B headers and H/E. Let me see if I can find a picture.

Jim, your description sounds like what I want to do. I'd like to take air from the engine out the left side where it would normally go to the blower, and drop it down around the dizzy to the crossover inlet. IT seems all of the backdate setups take air from both sides of the fan and go to the heat exchangers. I like the setup for the 964 on the link I submitted.

 This was the only way that I could figure to get the air blowing to the H/E. The part that Thom made directs the air too far to the left to work with a 3.2 I think. I modified part #930 326 01 so that it wouldn't hit the fuel rail or the dist.

Jim:
That's the setup. Do you have any closer pics of this?

I haven't finished the part, but this is my approach. I cut up the original tubes and am using this as a fiberglass mold...
 This was the fiberglass that I layed (sic?) up while the pieces were in the car...  I've actually replaced the entire plenum (what the tube connects to) now with fiberglass. I'm debating on losing the tube and going with a flexible duct. I'll post some more pictures when its more presentable and in the car.  At that point, I want to build up a mold to have a hose going under the plug wires.

einreb: that looks like a decent way to go. Maybe I'll look for some used pieces and give it a shot.

I did the same thing as 'einreb' and just built my own.

mark,
how did you fabricate that? (i.e. mold?) the only things I had done in glass have been pretty much 2 dimensional. -bernie
