Did 68 built 69 Camaros that came with this fan also have them date coded 69 or should they be date coded 68?

My understanding that there were two fan blades. One stamped and one that wasn't. The stamped one did specify the year (68 or 69) on the date code.

THIS might help Marty.

I guess I should have copied this onto my first post:

•The 3937779 fan was used early in the 69 production year (until approximately November of 68) and has the part number and month / year stamped on the fan blades.
•The 3947772 fan was used throughout the production year (and through the early 70's) and has the part number and month / year stamped on the fan blades.

Here is where I'm confused...The Camaro is a 12A {68} build. According to the information above, should my car have the 3947772 fan...Or is there insufficient data to pin down which of the two blades my car should have? "Approx Nov 68" tells me there insufficient data to tell when the transition occurred.

My other question...If my car is suppose to have 3947772 (which it does have) what month should be stamped on it. Would it be Dec, prior to Dec, or can it be another month in 1969?

Thanks Ed

My 11D L48 has the unstamped fan.

It could be either the unstamped fan or the 772 which *could* be dated 12/68, much more likely to be 11/68.

Boston...what is the date on your blades?

Thanks Kurt

Boston14 · « **Reply #7 on:** March 09, 2011, 01:26:01 AM »

Marty, it is the unstamped fan, no part numbers or dates on the fan.

Darn...was hoping to get a sense on when these blades were mass produced. My dilemma is that I have the correct blade but I'm pretty sure the date is way off...

Thanks Robert

I'm not sure how to make my post clearer.....

IZRSSS · « **Reply #10 on:** March 09, 2011, 01:11:57 PM »

You are right...

Anyone want to trade an excellent L69 for an L68? Mine is only off by a year...

KurtS · « **Reply #11 on:** March 09, 2011, 05:12:50 PM »

Watch ebay, they show up regularly.
I bet most people wouldn't catch that.

IZRSSS · « **Reply #12 on:** March 09, 2011, 05:50:06 PM »

You bring up an interesting point. A lot of car shows and their judges would never catch something like this. Many of the judges at these shows are only knowledgeable with regards certain makes. Even then, compared to members of this site are still lacking. If possible, I would like to here from AACA Judges and his or her experiences with judges of the same caliber. Are all judges {AACA} capable of evaluating every single item in the car for accuracy, and do they know how to decode every single numbered item down to the correct finish? Please be honest!

not sure of the change over, but my friends 01B 69 z-28 has an undated fan

KurtS · « **Reply #14 on:** March 09, 2011, 09:43:44 PM »

There was always an unstamped fan - that's how that supplier made them.
The only changeover was from the 779 & unstamped#1 to 772 & unstamped#2. They changed the pitch of the blades slightly.

9T4Z · « **Reply #15 on:** March 10, 2011, 08:48:50 PM »

I personally would keep the wrong dated 772 rather than the un-stamped 772. The unstamped 772's are a popular choice when they can't get the correct date. I know they are just as 'correct' but the stamp is a nice touch....

My car is 12a and has the 779 blade on it,the car was built in LA

Boston14 · « **Reply #17 on:** March 28, 2011, 10:48:44 PM »

The unstamped fan is not an unstamped 772 fan. It is a very different design. Check the pictures showing the two fans.

very interesting.... did not know that.

maroman · « **Reply #20 on:** April 03, 2011, 04:58:48 AM »

Marty, I'm NOT an AACA judge but have been to school a few times. They won't catch your fan's date and don't even check such things. A car can have ANY option or package available in the year the car is supposed to be. There is a WIDE interpretation her, options can be added, car can be painted any color available for the year. A six cylinder turned into a Yenco is OK with them.

IZRSSS · « **Reply #21 on:** April 03, 2011, 12:52:56 PM »

Maroman,

Thanks for being honest. As I mentioned before, it will be a while before my wife and I can make a trip to your neck of the woods for a AACA event. However, it is nice to know we won't need to spend 60 to 90k to be respectable. I had posed a question similar to this at my AACA/ISCA thread and you were very helpful then. You mentioned the main thing judges are looking for is Condition and Cleanliness, with deductions for after market gadgets or parts. I think we're one leg up in that category.

I would eventually like to give the National Certification a shot and I also think AACA would be great place to start. There is no question in my mind there will be plenty of qualified Camaro experts at this show who can give good sound advise. My frustration is that there is no one here in New Mexico that knows blank about these cars. In fact, even though my car did very well at the SW Muscle Car Nationals...it was a 69 DY Z that took best of show. Sad thing is that this car had many things wrong with it that I could see. I could only imagine what members here would have done to the car.

Thanks again...

Marty Do you have a pic of the "winner"?

IZRSSS · « **Reply #23 on:** April 03, 2011, 01:54:33 PM »

Yup...grill for starters and RS wheel well trim...Keep in mind, if Ed's 69 Y would have been in the competition he would have won hands down!

tmodel66 · « **Reply #24 on:** April 03, 2011, 02:42:06 PM »

I see what you mean Marty. It probably would take a beating if there were any detailed pics like the eBay auctions have.
Was he the judges brother-in-law?

Pretty close...one of the richest families in Albuquerque, and a sponsor...on par for NM politics... $:-\$
