Open air cleaner

[Joseph M.]

Having finished the restoration on my 67 BB we've moved on to my 70 Chevelle SS 396-350 HP coupe. I'm having difficulty locating an open, non cowl induction, air cleaner base. The base for the 70 Chevelle is apparantly a one year only item. I've posted on the Chevelle Forum without success. My question is might anyone have a cross reference on any other cars this base may have been used on? Thanks in advance for any assistance.

I can't find the part number of the 1970 with BB air cleaner base. However, the complete air cleaner assembly was GM #6485239 and it had no other applications besides 1970 Chevelle with 396 or 454.

Re: Open air cleaner

That's what I was afraid of learning. Well I know this is a Vette forum, but if anyone knows of a potential source for this base I would greatly appreciate your help. I'm still a Vette guy at heart.

Re: Open air cleaner

Joseph,

The 6485239 air cleaner assembly is listed in my 1970 Chevrolet Parts Catalogs (Jan. 1970 & Oct. 1970) and 1972 Corvette Parts Catalog (sept. 1971) for the following:

1970 Chevelle 396 (exc. SHP & exc. Spec. Duct Hood)
1970 Chevelle 454 w/H/Per. (exc. Spec. Duct Hood % exc. Monte Carlo)
1970 Nova 396 (exc. SHP)
1970 Camaro 396
1971 Corvette 454 w/SHP

The 6485239 Air Cleaner Assembly is also listed in the following:

1970 Camaro AIM, UPC L34, sheet A7
1970 Nova AIM, UPC L34, Sheet A6
1970 Chevelle AIM, UPC L34 (LS3), Sheet A7

CORRECTION:
Enclosed is a photo of what I believe is a base from a 6423272 air cleaner assembly that is very similar to the base of a 6485239 air cleaner assembly. I believe that the base of a 6485239 air cleaner assembly has a "radial" tube that extends about 1" beyond the lip. The "radial" tube on the 6423272 air cleaner assembly is much shorter.

Air cleaner bases are located in Chevrolet parts catalogs in Gr. 3.406. I do not believe that the base for the 6485239 air cleaner assembly (shown in Gr. 3.402) was ever sold over the counter. The outlet tube is in a "radial" position.

The 6485239 air cleaner assembly was discontinued sometime between Jan. 1982 and Jan. 1990.

Re: Open air cleaner

Dave, thanks for the great information. I'll search for the base using the additional info. The pic you posted is like the one I need. I'm sure there's one out there.

Yes, I checked further and confirmed the 1970 Nova, Camaro, and 1971 Corvette LS-6 applications.

Re: Open air cleaner

There is a photo of the bottom side of a 1970 Camaro L34 air cleaner assembly (6485239 air cleaner on left side) shown in the link below (posted on 04/07/2012 @ 1:17:58 PM).

NOTE: The "radial" tube on the base of the 6485239 air cleaner assembly extends about 1" beyond the lip.

Joseph,

Note that I made corrections in my two previous posts. The "radial" tube on the base of the 6485239 air cleaner assembly (see my post @ 10:55 PM) extends about 1" beyond the lip. The "radial" tube on the base of the 6423272 air cleaner base (as shown in the photo on my post @ 10:15 PM) is much shorter.

Sorry about the confusion.

I think the only significant difference in most of these air cleaner bases is the configuration and angularity of the tube(s).

[Dick W.]

Re: Open air cleaner

I believe one of the vendors sells the tube separately. It is not a major task to replace/move the tube. We repaired several when we had the restoration shop.

Re: Open air cleaner

Thanks for all the responses. I think I found a base, but I also have to purchase the lid which I don't really need. I guess I can just sell the lid to someone that needs an original. I assume the lids were interchangeable between Chevelles, Corvettes or Camaros with open air cleaners.

Yes, the 66-72 open element air cleaner lids were all, essentially, the same.

Re: Open air cleaner

there is one for sale right now and no they are not the same, the tube has a different length and angle than the rest of these
