Nice job! It’s fun making things on the lathe.
Why did you choose to use a pin wrench fastener instead of the original slotted style?
I chose it because I think it looked a bit more period correct.

Nice job, @mnkyprod .
But, since you've opened the door to 'period correct', I was wondering if anyone has tried these replacement air cleaners (for Webers) from Vintage Speed. I've got the chrome ones from EMPI (similar to what you have on your Kadrons) and was wondering if these are as 'plug and play' as claimed.
Sacto MitchI like those air cleaners. Not sure if they are only for Weber carbs.
The Kaddie Shack https://www.shopkaddieshack.com/ sells different air cleaners for the Kadrons if you are looking for something other than chrome.
In a perfect world, I love to have velocity stacks, but have yet to find any for the Kadrons that don’t attach using hose clamps (like the ones the Kaddie Shack offers).

I have a set of those on my Webers in my Beck. They are a nice addition and look great. I always liked the vintage 
look of the air cleaners often seen on 4 cam engines.
@IaM-Ray posted:Those are really nice, but Stan and others... I believe use a carb cover that has a pipe to direct backfiring episodes safely without burning up the car. I would investigate those before committing.
FYI I think they were available from Pat Downs !!!
Those are CB Performance Turbo Hats.

Are those Knecht knockoff air filters oil bath like the originals or do they have a paper/foam element? If the former they’re probably only 50% better than running open stacks, provided your engine compartment is fully sealed from below. (If not,all bets are off)

You know, a real enterprising fellow could engineer a modern air box that housed a flat filter directly under the air intake, and routed intake air through hoses to the carbs. Eliminate warm engine compartment air almost entirely.
No idea what that would do to the whole intake airflow equation. My real world experience has involved going the other direction: opening up air boxes (968) or removing them entirely and replacing them with pod filters. (Ducati)

They use the stainless steel fire retardant filters seen here.

Yeah, but that might block off too much of the cooling air. I once saw a Ghia that was doing something similar, but was pulling the air from down next to the transmission.

There's no bath involved — except for the one you take when you write the check. They're currently $500 the pair.
They come with some kind of "simple, foam" filter, but will also use EMPI or K&N elements. And that's another $150 if you go with K&N. So, I was hoping to hear from someone who could confirm they really do bolt on without any surprises.
Their 'installation instructions' link leads to this:
I'm hoping that little blue drawing isn't what your carb looks like halfway through the installation.
In particular, they would rest right on top of the support plates for the hex bar linkage, and I'd rather not disturb those if possible.
Also, it looks like the little vertical support rods inside the housing come really close to the velocity stacks, so probably need some filing down for clearance. Not a big deal, but I'd like to hear from someone who's been there.
Anyone?
I'd also like to confirm that these things seal well against the bottom and top of the (K&N ?) filter element. This is really critical. The slightest gap will let small dirt particles through and the next place they end up is in the float bowl, thence on to the passages that the jets draw fuel from.
My current thinking is that this is responsible for most of the 'dirty fuel' problems we hear about. I've never really understood how even fine granular stuff can make its way through the paper element inside most fuel filters. Dirt entering through the air cleaner this way would never have to pass through a fuel filter.

This website has a good picture flip through of the installation and whether the supports come in contact with the velocity stacks. The base of the air cleaners seals to the top of the carb using a paper gasket, and the bell size or width of the velocity stacks determines if there will be contact with the supports or not. The filter seals tightly top and bottom when the top screws are tightened down onto a k/n style filter element.

I installed those on my Spyder. Install was semi-simple to change over from the CB Performance filters. I used the CB bases to keep the hexbar linkage simple. I also had to grind a little relief on two of the velocity stacks to clear the bolt-through thingies on the air cleaner housing. Used the paper filter elements from the existing CB setup but installed the wire mesh outside. Fiddly to get it all tucked in neat, but not terribly so.

Ed, thanks. Just the feedback I was looking for.

LOL. That’s what I thought when I first saw them, but boy do they look the business.
mnkyprod: Your bezels show you've got skills, really nice work.
