Help Identify Parts...
 

Did a little house cleaning and I need help with a few parts...

First is a dual snorkel LT-1 style air cleaner...I have had this for about 25 years. Only marking is a stamp on the bottom with CHO lettering...

Next are two five blade fans for a clutch setup...center to center is 3" on both.

One has the word FRONT stamped on it and an "H"...rivets are rounded...approx. 18" across.

Second one has no lettering I can see...rivets are flat...17" across.

Any help is appreciated.

67 camaro air cleaner decal. Not the air cleaner just the label

I believe the letters would be CHQ for Camaro Headquarters. The lid appears to be repop, but difficult to be sure based on the photo. Can't help with the fans.

The fan blade on the left. Is that one of the mega buck crazy looking rare blades for a 67 L78 Camaro. I’m not sure about its part number.

The L78 fan had a larger opening and the center to center was 3.25".

I think the letters are CHQ...probably a repro unit.

How many rivets would the correct fan have for a 67 L78?

High Horse Fan Blade
 

Pretty sure it has 4 rivets...

CRG info...

Fan for L78 and Z28 and 1968 L34/L35 with K02
The 3871276 fan was used on the 1967 and 1968 Z28 and L78, as well as 1968 L34/L35 with K02. The bolt circle diameter for the clutch-to-fan attachment was 3.25-inch. It thus required a different clutch unit than the fan clutches used with the AC or K02 hydraulic lifter engines.

My 68 Z28 uses a 4 rivet fan and the smaller hub.
I have an NOS 4 rivet fan and matching clutch. Posted here a few weeks ago to determine application.
