Hot Rods old air cleaners

I just picked these up ans was wondering if I could tax your memory on what they might of came off of, they are marked chrysler imperial, but I don't have any idea if they were both used on the same car as a pair, and what year imperial they might have been found on.

 

Looks like the letter A after 300, that would be the first year for the 300 letter cars, 1955.
Dual four barrel intake would use both.
But I have never seen those before

 

Thanks Paul. does anyone have a picture of them on a car??

 

Looks like it says Impco Natural Gas
Very interesting..

 

Toward the bottom it says-
Impco Natural Gas
I think they were never on a Chrysler, more than likely they were on an industrial application or maybe a truck.

 

Or forklift.

 

Vry cool guys thanks that help alot. you guys rock.

 

Here's one on an OT (1970) Ford

 

These are the only type I know of used on cars.

 

I agree, they are not Chrysler product.
They are Impco propane conversion pieces.
Interesting they say Imperial 300A

 

One of my favorites, purely because of the simplicity of it. And it is old.

 

Definitely says impco on them

old propane carb hats, still cool beans I would pull them apart and see if you can stuff a filter in them and use them.

 

Here you go @Tim

 

The first ones, at the top, look really over-built..... but in a good way, solid.

 

Once upon a time Propane was the 'go-to' fuel for farm equipment, especially tractors. As a result many pickups were also fitted with propane --- a clean burning fuel, that reduces carbon build up and therefore engines using it required less maintenance and down time, certainly a plus in once a year harvesting and cash flow. It has also been used to make diesel more volatile and clean burning, and was used for a time at Bonneville on the super-charged big rigs that ran pretty fast. I kinda think this is a little 'off topic' but the diesel engine has been around since the beginning of automobiles, so in that sense, it is traditional, though certainly a specialized area.

 

Smokey Yunick did a lot of work on running engines on propane. Also Chet Herbet's Jimmy powered 32 sedan.

 

I wonder if this ford engine was running on propane?

 

Yes it was

 

Impco LPG (propane) "snorkels" - I have used these on LPG conversions several times. I have thrown out a few of these, now I'm looking at them differently.

 

This type is common on tractors

 

that’s a really neat filter
But it’s only a pre filter , still need an element down stream in the intake system.
Used in very dusty or dirty environments
Like manyolcars said seem a lot on tractors.

 

Those are rare and classy looking filters. Good score!
