65 365hp cooling fan 5 blade no A/C?

[Jim R.]

I'm going to try and find a original fan blade for my 327 other that the 17-1/8 diameter and 5 flat rivets per blade and the blade dimentions of 4 inch by 5.68 inch, is there a H,W or FRONT stamped in the blade. thanks JR

I believe the stamping would be on the hub not the blade. Expect to see"front" and a H on the front side.

The original fan on my 1966 w/327 (built Feb. 1966) is stamped "H" (Hayes-Albion, the manufacturer) on the front and "W" on the back side on one of the "arms". The fan does not have the word "FRONT" stamped on it. The fan-clutch is stamped "SC 1-26-66" (Schwitzer, the manufacturer dated Jan. 26, 1966).

I have other Hayes-Albion fans from other Chevrolet models in my collection and some have the word "FRONT".

They're looking for FLAT head rivets now ? Believe this was off a '64. No FRONT or W on this one; just the H.

Wayne,
I think the "W",or "H" is the manufacturer's ID. Just out of curiosity what year car is this fan in the photo from?

Gene -- could be off a '64 VIN range 086xx or a '65 101xx. I bought the advertised AM/FM radios out of these two cars; father & son were converting their stock cars to resto-rods. I threw in a couple of hundred $$$ more and they included a bunch of black steel rims (no '64s ) and boxes of other parts that they wanted to get rid of. Fan came with a nice 3770245 pulley (before they started to stamp the part #) and a decent clutch.

The current '65 JM has no mention of any stampings. Of course that may change when the next revision hits the street.

It does mention mushroom head rivets and the dimensions given by Jim in his original post.

The old 65 judging manual called for flat head rivets and you new one say's they call for round mushroom head rivets?

The one I'm quoting from is 1965 5th Edition Judging Guide that is the what I believed to be the latest. There is a newer one in the works however that has not been released.

Who's on first, sounds like some spinning on rivet heads.

Wayne I have two 65 BB fans . one has flat & one has round rivets from #16120 &#17346 .

Re: 65 365hp cooling fan 5 blade no A/C?

Jim, original '65 five bladed fans should not have the word FRONT on the face of the fan. When we researched for the re-write of the new '65 chassis section we discovered that either flat or mushroom headed rivets are original to '65.

Hope that helps.

Tony . Why do you think the 65 BB fan did not have the word front ? I have one with & one without . If not what did it come off of ? was it a service part ? I thought the 65 BB fan was all by itself in size & pitch . What was the size and configuration of a 66 BB fan ? My fan was on my 65 when parked in 1973 with 31,000 miles . It also still had its orig. fan clutch , water pump ,shroud & radiator . If its not orig. to the car what do I have ???? Bill

Fan GM #3872792 was used for 1965 L-78 and was unique to that application. However, it is very similar to fan GM #3888366 which was used for 1966-67 big blocks (as well as many 68-69 applications).
