I'm looking for one of these dated late 69 thru Jan 70. It's for a Feb. 2, 1970 car. Thanks

The correct water pump for a 1970 Corvette LS-5 is 3940960 regardless of AC or not. The one you listed is for 1965-1968 Mark IV 396s. Reference 'Chevy By The Numbers' and the 1970-1972 Corvette Judging Guide, 4th Edition.

That water pump you listed will work for a 1970 LS-5 but is not correct.

I was looking in the NCRS Judging Manual 3rd edition and it listed the 3856284 water pump. Must be a misprint. So I guess I am looking for the same one you are. Thanks

No, not a misprint in the 3rd Edition. At the time that water pump was accepted as being correct. Many of us began to question that entry including former NCRS judges and rebuilders. There are several corrections made in the 4th Edition. Can't wait until the 5th Edition comes out. However....if you have one that came off your Corvette then you can get some decent money for it as is. Check eBay for listings.
