Just to add:
Air Condition Equipped Cars also used the #3947772 7 blade Fan too,as well as ALL w/Solid lifter engine for those years..I have never seen a #772 Fan w/o a Date or part# on it.
The 1970 L-78 Chevelle received the #772 7 blade fan.
The 1970 LS-6 Chevelle received the #3976064 7 blade fan,(no date or part# on it),but some Very early built ones got the #772 7 blade fan also.

Wayne, Allen graciously posted pics of the correct fans, straight cuts on the bottom of the blades and 5 rivets, dual bolt pattern is a over the counter "crash" part I believe. Good job Allen. SULLY

I was living in the Phoenix area for 8 years and met a guy that had a original 60K mile 70 L78 Nova with all the paperwork, POP and Window sticker (Before Repops)Late 70s originally sold through Courtesy Chevrolet that had HD Cooling on the window sticker (do not remember RPO # and had the 7 Blade 772 Clutch Fan and 4 Core radiator in it due to the high temp.s. Also had seen the COPO radiator installed on another probably dealer installed. GM had a proving grounds in the area they could have had some influence on cooling these solid lifter motors in the AZ. heat. Too bad there are not any of these GM proving ground guys out there to verify a few things. Seems like the Hobby does not have the luxury of speaking with actual X GM employees, assembly line, and proving ground workers enough to dispell some myths.

Many thanks for the pics!! Just what I needed to see.
I've saved them in my Nova fan file for future reference.
My eBay fan will be delivered Monday and will post pics for your perusal.

You guys are confusing me. Marlin's reference is to the Deuces.

So what you are saying is that every Solid lifter car produced by GM in '69-'70 received a 772 clutch fan with or without a date or part number other than Novas w/ L78s?

69 & 70 BB Novas used a non-clutch, 5 blade fan, (I believe without a part number or date).

70 COPO - solid lifter Novas used a clutch, 7 blade fan, without a part number or date code stamped into them.
