69 L78 Nova Fan

I have seen only a 4 blade non clutch setup on early cars and then a switch to a 5 blade non clutch set up later in the year. I have never seen a 772 clutch style used on a L/78 Nova. Ask Rowdy Rat to help out too..BKH

I have a March built 69 L78 Nova...It has a five blade fan.

Thanks for the info my car was built in May 69 so I assume it would have a 5 blade fan. Do these fans have a part # and a date code ?

I am unware of any #'s on those blades...BKH

Found the P/N on the 5 blade fan on my 69 Nova L78.
It's 3947824EV Can't confirm its the original however.

Martin,

The 3947824 was replaced Mar of 1970. The 1970 L78 fan switched back and forth with 2 different part numbers for a 5 blade fan. Which is typical depending on the source of the part. Have you check an assembly manual for 69?

Those part#'s you are listing,are not Fan part#'s.
*3947824 is a 1969 Assembly line B/B Deepgroove Fan Pulley.Used on Special Hi-Perf solid lifter engines.
*3976060 is a 1970 Assembly line B/B Deepgroove Fan Pulley.Used on Special Hi-Perf Solid lifter engines.
The Fan is a different part # altogether.
