1970 340 air cleaner dimensions?

This is what it looks like with the snorkle removed and the lips hammered flat. No way to repair that to an oval.

Yeah it will need an insert welded in. I was going to stop by Metal Supermarket today but my Jeep Cherokee blew an upper rad hose when I was on the other side of the city so the plans changed. I lost most of the coolant but it seems to have survived. Design defect I am sure.

ps what do you think the radius is where it turns in....1/4" or bigger?

I'd say 1/4" maybe. I can't remember if I measured it or not. I do remember that I used masking tape, to tape into the oval opening all the way around. I cut it even with the inside edge all the way around the inside. I then peeled it off and stuck it on the side of one of the orange air cleaners to see what the I.D. of the holes at the end of the ovals would be. It didn't work out like I thought it would, so back to the drawing board.

Would a carbon fiber mold that was formed to the inside of the oval openings be strong enough to hammer the lips into shape? If so, I would be interested in one or two if you make some.

So the mold will be 3d printed using PETG plastic, which might take the abuse of being a forming buck for the radiused holes. That you could then tack into a housing. You would need to go slow. Pretty sure I will make the housing mold without the holes. Then make another mold to make the holes. Then epoxy them together. Just easier to print the mold. Once I draw the holes, I will print one at 100% fill. Strongest setting. It might survive using a shop press to stamp a radiused hole.

Before I got started fixing my leak Jeep this am I made a crude wooden buck using a router and hammered out a piece using 22 gauge sheet metal. Its pretty crude but I wanted to see if there was any possibility of this working before getting too fancy. I think it might work. The buck (ok an oval hole in a piece of plywood with a radiused edge) is flat so I'm worried that I won't be able to bend it properly for the 8.5" radius. There is no hole in the air cleaner yet for me to try and fit it. I would then have to make a radiused buck which is a bit more work. I only need to knock out 2 of these so we will see how it goes.
