Crossram air filter?

About 20 some years ago I bought what is supposed to be a crossram air filter. I haven't bought the air cleaner yet so I don't know if it is the correct one. It's a Baldwin Filters PA632, 9 3/4" x 20 5/8" x 1 3/4". Can anyone Please tell me if this is correct? I've seen some sellers have a 3" tall one would this be a better filter to run? Thanks...

There must be some guys out there running crossrams ? Can someone please look at your filter and give me a size? All I need is the measurements.

Re: Crossram air filter?

Jim this is directly from Wayne Guinn's website. Wayne is the Camaro crossram "guru" IMO.

The element used with the plenum air box, Chevrolet PN #3942572 (Purolator AFP 22) was 1 1/2 inches high by 53 inches in circumference. This yields a total breathing area of 79.5 SQ.IN. As a reference, the standard four barrel air cleaner for the 302 is 3 inches high by 44 inches in circumference and yields 132 SQ. IN.! Yes, the initial 2X4 element was restrictive in terms of being able to flow 1200 CFM AT 7200 RPM. In contrast, the element that was used later (Second Design) in conjunction with the fiberglass hood, Chevrolet PN# 3963825 (Purolator AFP 66) was 2 1/2 inches high BY 53 inches in circumference which yields a total of 132.5 SQ.IN.

The Baldwin filter specifically I can't say if it's the same or not.

Re: Crossram air filter?

Dave,
Thankyou so very much for your help and telling me about Guinn's Eng. His site showed me that on reproduction air cleaners the Baldwin PA-632 takes the place of the original Purolator AFP-66 filter. This tells me that I do have the correct filter. Now I need to find a good quality reprodution small base air cleaner with nice chrome. I had one in the past, but sent it back because the chrome top was so poorly done.

Wink Re: Crossram air filter?

Jim glad the info helped you prove you've got the right filter. Wayne is a good guy and he's done an excellent job collecting and sharing a lot of the history for all the enthusiasts. I'm sure someone on this site can help you with locating a high quality air cleaner for your set up. Maybe it's possible to go back with the one you had and just have the lid rechromed? Good luck with your search.
