Pics of 67 427 fan?

[Patrick B.]

Does anyone have any pictures of a correct 67 427 fan? I'm trying to identify what I hope is my original fan from the various stuff in my garage. My best candidate has a W on the back side of one the arms, H and "front" stamped on the front, but it seems to be only 17" rather than 17 1/2" in dia.

Patrick,

It's Part# 3888366 with a "H" and "66" and "FRONT" on the center hub ring side and some other telltales. Pics Here and Here.

Also Search "3888366" and you'll get more info.

The car does not have A/C but other discussions on this board said A/C didn't change the fan. The rivets are flat and it looks like Richard's except there is no "66" stamped on it. But is seems to be only 17" in dia. There are no numbers stamped on the blades. I will not be home for a couple of weeks but I will post a pic when I return.

Without the "66" and at 17" OD it's most likely a GM #3770529. This fan blade was used on many 61-67 small blocks but never a big block. It does have 5 blades like the 3888366 but the pitch angle of the blades is less. The 3770529 is still available from GM; the 3888366 was discontinued more than 45 years ago.
