Four port smog canister

[DEUCE]

I have a four port smog canister and I am wondering what the application and value of this piece is. I was told it's for a 70 Camaro or Chevelle. Just looking for some direction. Thanks in advance for any info.

I don't think that's for a 70 as 1970 models with the NA9 California Emissions’ Evaporation Control System had 3 ports, (See Photo)
Might be later like 1971 or 1972 so value may be low IMO

I believe 1970 Camaro's with Holley carbs (Z28, L78) and NA9 California emissions got the 4 port. All others got 3 ports.

A little hard to see the top in this photo, but you can see the 4 hoses going to it:

Thanks to Rick Nelson for the photo.

If you are interested in selling I may know of someone.

Actually my bad,
Re checked my files and it looks like the solid lifter motors with a Holley carb had a 4 port system while the Q-Jet carb got the 3 port system. Sorry about that.
Photo is from a 1970 Magazine of a LS6 Road test.

So for Value I am going to say $60 to $100 for a used one like yours IMO

There should be a DATE - in Julian format on "melted" into the top of the can somewhere- like this.
