66 327 4bbl air cleaner question

[1966burb]

Can someone provide a picture of the correct air cleaner assembly for 1966 327 4bbl.? This is one piece that came up missing since the last time I owned the suburban. I am sure it was a single snorkle, dry element of some sort. Hard to find??

I believe this is the style of air cleaner that was originally used on the 327 in 10-30 series trucks in 1966:

As is listed on that site, it was also used on some 64-66 car 283's and 327's so they're not too hard to find if you are wanting a good used original as opposed to a reproduction. Good used 4bbl bases are a little harder to find than the 2bbl ones. Lids are the same for 2 & 4bbl although there were a few other snorkel styles used for other years/applications.

Exact same air cleaner on my 65 Impala 327 4BBL. If you need pics or measurements, LMK. Note that the base is for the Rochester 4GC, and it won't fit larger later 4BBLs like Q jets, Holleys, Edelbrock, etc.

Thanks for help. Yes, I would like to find a nice original. j

If it was a original calif truck it would have a different base same top

This is very important. The correct, original style air cleaner won't work on anything but a 4GC carburetor.

Does anyone out there have an air cleaner base for a 4 jet carb that I could buy? I need a base to cut apart and weld to a larger based air cleaner. it is the 50's Cadillac type that I have painted and pinstriped. I want to use that original carb, and also want to use the air cleaner I have. An old base in decent condition would be fine.

Does anyone have a pic of the original california 327 air cleaner? Mine is an original 327 fremont california emissions equiped truck, im interested in seeing what the correct air cleaner looked like.

My Impala is a California built/delivered car, not sure if that will help.

[1966burb]

How can you determine if your truck was CA built? j

[yelmer]

your truck could have been built in cailf . but could be shipped to other states . most all went to western states . I live in Colorado and we received fremont ca trucks here. if it was shipped to a calif. dealer it would have the air cleaner for cailf stds since it would be sold in that state

[yelmer]

if you have a z in the serial number it was made in ca if it is a suburban it might have a b in the serial number which is Baltimore md . I think most all suburbans were built in Baltimore , but I am not positive on that

[yelmer]

yes another one

[1966burb]

My oil cap is the push on style. What does that mean? Did all the air cleaners have that hose connection on the base?

[yelmer]

no they did not if you have a push on it is not a closed positive vent

[cortcomp]

Mine is the non-vented one with a hose and pcv valve coming out of the filler neck. I also have the manifolds for the air pump injection.

[yelmer]

send some pictures

[cortcomp]

it's at the machine shop right now, but i still have the manifolds at home, can send some pics of those.

[1966burb]

My PCV comes out of the back of the carb and runs to the rear of the engine. My exhaust manifolds are drilled for air tubes, but are plugged. I will take some pictures.

I was able to pick up a nice restored air cleaner on CL yesterday. Someone did a great job of modifying the base to fit a Q Jet carb. I will need to trade that off for an original base to fit my smaller Rochester carb.

[cortcomp]

I have a 4jet base that came off my truck but its not the correct air cleaner and someone connected a pipe plug to it underneath. Perfect for cutting up. Pm me your email addy and i'll send pics.

Man that's a nice air cleaner too!

[1966burb]

The guy said that it was painted at a body shop. You can tell it is not a rattle can job!!

1966burb: Have a machine shop turn up an aluminum spacer ring. Then you could keep it and maybe use it on another carb some day. I want to modify mine, but dont want to cut it. Mine needs to be bigger. What size hole do you have? I might be interested in it.

[1966burb]

This is how it looks modified for a Q jet.
