1970 340 air cleaner dimensions?

Going to build myself a Duster………how hard can it be? :) You forgot about the Carbon Fiber itchy tax! Nothing worse than CF itchy!
 
Is this something you will be selling?
Long story-long, not really. I don’t make pretty CF things, everything I make is painted and has a bit of body work to it. Also, my molds are single use only because of the straight draft of the housing makes it almost impossible to get the part out of the mold without destroying the molds. Because my 3D printer is not huge, it takes making an 11 piece mold just for the base and another 11 piece mold for the lid. Each piece of the mold takes 16ish hours to print. So again long explanation, but not really. I will probably have 150 hours in it and $200-$300 in materials. Now a bunch of that was drawing it in CAD. I have ulterior motives to make this one. (I want 9’s from him) The thermoquad insert, sure, just need to make sure it fits to the transition of your current base. My AVS insert was good for 5-8 hp, did slap the air door open much quicker and it went a full point leaner. So had to add a bunch of fuel. Not sure what the Thermoquad one will do. In the end, the part would be hideously expensive to make it viable and I don’t mind screwing Brian, but regular people, not so much. Actually if you can 3d print, all the molds are public access in Onshape. I use the free version, so it is open access. Then watch videos to learn CF, not that difficult. Sorry such a long winded answer. Anyone interested in CF or printing molds. Reach out to me, it is NOT hard to do or does it require a big investment. $130 for a HF a/c vacuum pump and $180 3d printer and CF is $25 a yard x 50”. I’ll answer any question I can. It is not hard!

One option is to bond cf or glass intake ports into a ‘72 housing which should be more economical. I have fooled with making sheet metal ports but I don’t have a shrinker right now and have another big project on the go.
 
I’m pretty sure a 3d printed mold and a shop press will stamp out very good window opening.
Here’s a proof of concept.
 

Might be able to help with the mold/dies Printer working overtime right now. A regular shop press would probably be enough.
 
With the dies you designed and showed back in posts 47, 48, 49, would one of those work to stamp the hole into an existing air cleaner on the passenger side? The drivers side will probably need to be stamped into a flat piece of metal and then welded in. Of course, proper size oblong holes will need to be cut in both parts to be stamped first.
 
I think they would work on the housing itself. Just to to be able to set up a stand in the press. Slide steel through the center hole and stack a block high enough to support the inside die. Have a couple of things I need to print first. I think the snorkel ones would leave a small notch in the corner of the radius due to how the hole is stamped.

I think this project is over for me. I have located a reasonably priced 340 air cleaner. I'm glad I didn't cut up the trap door air cleaner which is now getting primed and painted.
