Technical Least Restrictive Air Cleaner for 97'S

What is the least restrictive air filter / cleaner for Stromberg 97's ?
I am running two 97's and the ones I have are causing rich conditions.
I am using the 2" x 3-1/2 " paper units now. Thanks for any info.

 

One of the members did a flow test on filters just a month ago or 2. Search for "flow test" might bring it to the top.

 

My neighbor has a flow bench and uses it. He told me that the plenum I created was good. I laid a flat plate over my 3 deuces, with a hole for each carb, used 3x2 air filter (62 Ford 406??) and added another flat stainless steel plate as a top. Easy, effective. No photo

 

Here is that link I mentioned

Go TALL. More surface area = less restriction.

 

Use the Wix Filter site, https://wixfilters.com/Lookup/FilterBySize.aspx and cross reference what you have. Most listed also show CFM ratings of the filter, use that for selecting a more appropriate filter.

 

K&N filters pretty much outflow everything else out there.
Just make sure the housing doesn't become a bottleneck.

What filters are those? Thanks

 

Don't know how they flow but I sure like the looks of these:

 

I use filters for commercial air compressors.

 

I have used K&N filters in everything I own since I started using them in my motorcycle racing days in the 70's. A fully dirty K&N will flow slightly less than a paper filter when new. I am currently running K&N filers on my F250, my wife's Mercury, my OT El Camino and my avatar hemi powered deuce roadster. K&N guarantees then 10 years or a million miles. Pricy, but good stuff with plenty of copy cats out there.

 

Size for size K&N to compare to others brands ,
or just a mesh screen

 

Thanks all! Looks like K&N
