3927792 Fan Spacer on Small Block?
« on: April 17, 2023, 10:21:09 PM »
Can someone with an SS350 w/o AC take a picture of the fan spacer on their car?  I can't believe that the 3927792 - 1" spacer is correct.  Mine is almost twice the length and the fan fits just inside the fan shroud like its supposed to (which I believe is a 3927794 - BUT it's supposed to be used on a 6 CYL?).  The larger one has been on the car since I bought it...something's not right.  I believe the chart below is in error.

Are we sure 3927792 is correct?      Just checking.  Here's the chart in the "underhood" section.  Maybe the V8 for 69 is for a big block car?

Four-Bladed Fan Spacer Part Numbers
Year       Application   Part Number   Length (inch)
67-68         6 cyl.      3876828         2-9/32
67   V8 (exc. 396)   3814241           1-15/16
68   V8 (exc. 396)   3857041           1-17/32
67-68   396           3857042           1-9/32
69         6 cyl.           3927794           1-1/2
69           V8           3927792             1

That's from the Cooling article.
You can confirm them - the part #'s are listed in the AIM.

Sorry Dave - 1969.

Kurt - found that info in the AIM - I never thought of that...(duh)....BUT - on line #2 of the Revision Block - 3927792 replaced 3927794 sometime early during the production run. Can't make out the date of the change.  Interesting.

I would still love to get some pics.  When I'm in Carlisle, I'll look at some cars.....

Thanks!

Not that this really helps, but found these at Carlisle today. Marks Camaros-used parts.
