Default WTB 454 water pump # 3940960 1970

Looking to buy a “C” or “D” date code 1970 water pump #3940960 rebuildable core or rebuilt unit. I have a C 70 block and a D 70 block. My car was built in July of 1970 - last month of production for the 1970 model. I’m trying to put together a period correct “512” block. Currently have a CZU 4 speed block and also a GCW automatic block.
Let me know what is available. Was advised by forum member that the 3856284 was not correct waterpump for my build.

Respectfully,

Tugboat53

I am not completely sure but I think the 70 454 used a different coded water pump. I could be wrong but I thought by the end of 1969 they stopped using the 284 water pumps.

My car was built in late July 1970 - what would be the correct number then ? Please convey any information that identifies the correct pump information. This “284” number is the only number that I was able to come up with my limited research information. I’m building a driver car but want to get it period correct. Thanks for your observation and input.

Thanks and Respectfully,

Tugboat53

You should be looking for a 3940960 casting number

Are you looking to sell one of the 512 blocks you have?

Ray, Thank you for interest and input. I was not sure as I had consulted a reference named “Covette By The Numbers” publication. May I ask you to direct me to your references? I am going to change my add to reflect part # 3940960. I will sell the GCW 512 block if I can make my CZU block work with my heads and intake dates. My car is a 4 speed car so the CZU is more correct but is an earlier dated casting. Again it’s a NOM car - boo hiss but it’s as close
As I can get to period correct. Stay in touch and I will advise what I will do with the extra 512 block.

Thanks again,

Respectfully,

tugboat, don't know if you saw it or not but bill mock has one listed on the ncrs site. a little pricey but I bought a small block pump from him and the restoration/rebuild was very nice.cant read the date on it you might have to call him to get that that.

Please PM me the information regarding the the block you may have for sale.

BTW.... I have a November of 1969 rebuilt 960 water pump if you can't find something dated closer to your application.
