Do these '67 327 a/c fan blades look correct?

[Rick #42561]

Is this the right fan? The rivets look ok, but the blade tips look different.Thanks.

Rick......... the shape looks incorrect.....and there are normally 5 rivets per blade for attachment...in either a tree pattern as you have or a dice pattern on the alternate blade. Also, depending on AC or not, the diameter varies.....Craig

Thanks, Craig.

Noland's book shows a 3789562 as one fan p/n for some a/c cars, and there is a blueprint of it on p.118 which shows the exact same four rivet layout as the unit in this picture, but the blade looks entirely different.

As you say, the a/c cars also had a five-rivet 3863137 (p.340)which has the X-style rivet configuration. The blades on both of those fans are similarly-shaped although the size is different.

This one is unfamiliar to me, and I wonder if it's off another GM line. And maybe they bent the tips back (the wrong way?) for clearance.

Any ideas are appreciated.

Not to reply to my own post, but I just ran across a '65 a/c car with the same fan unit. Unfortunately, all that proves is that they made at least two of them.

Anybody have or know of one on an original car? TIA.

Rick - I have been messing around to get the correct fan for my 67 AC L79 coupe for years.......somewhere I have the pictures of all the fans I have....including the two you mention.......I will try and dig them up for reference so you can see. As Joe says.....[none for sale].......since they are for my car....Craig

Rick. send me your email address.

Rick. Your fan is incorrect. Send me your email address and I'll send you a photo of a correct A/C fan for a '67 s/b car. I just went through this. I have an original '67 with factory A/C along with the correct fan.

Best,
Tony

Doc, if you are talking about the rubber air dam I believe it on backwards.
FYI I could not view your (Doc's) picture's.

I agree with that.

Rick - From you photo the fan blade assembly looks like the configuration of the fan blade assembly used on 1964 and 1965 Corvettes w/ C60. I'm assuming it's a 7 blade fan. As Craig pointed out it's not what one would expect on a 1967 sb Corvette w/ C60. 1967 sb Corvettes w/ C60 used one of two fan blade assemblies and both were 5 blade fans and 18" in diameter and used 5 rivets to attach the blade to the support arm. Check out page 218 of Noland's book. Anyway, if what you have is 18" in diameter, has an H and a 6 (could be a 9) stamped on the front of the center support and a W stamped on the back of one of the support arms, I'm quite sure it's the 1964-65 Corvette C60 fan blade assembly. Have fun. Pete

Thanks to everyone for the help. Peter, I must have missed that p.218 drawing in my haste to find a solution. That's the fan, and the other pic that I had in my files was of a '65 sb a/c car.

Geoffrey, thanks for explaining why the shroud looked wrong to me. At this point, I don't know whether it's repro or GM, but I'll try to find out.

An explanation is due: the pic is of a car I'm considering purchasing, but I haven't seen it in person and may not be able to. The unusual fan, shroud install and possibility of a non-original radiator may or may not suggest other problems such as front end damage of which the current owner may well be unaware. I'll explore the issues further.

In any case, I'm grateful for the help and don't want to wear out my welcome with such questions. However, I also don't want to make a big mistake. It's one thing if you know the situation going in, and ten others if you end up with surprises after purchasing a car.

Thanks, all.
