I will appreciate member's help identifying the following components and part numbers please:

Distributor #1111042

Waterpump # 398021F or might be # 393021F

Carburetor # 7040256X (Service replacement?)

The part numbers are taken from a 1970 442.
Thanks as always!!!

 

My reference shows the distributor as correct for 1965,66,67 400 engines depending on the date code stamped after the application numbers. It would be a combination of numbers and a letter. The water pump number you posted looks like the block casting number on the shelf above the water pump. Check the thread for a water pump for sale by kennybill, that will show you the correct location for the water pump number. The carb number is a very rare number, but being a factory replacement carb would drop that significantly but still a rare number. That number is for a 1970 442 W30 with a manual transmission. Let us know if you have any more questions. If there's any doubts, please post photos of the numbers/locations your looking at on your engine.

 

Photograph of the waterpump. Thanks!!

 

Yes that's the block casting number. Check this thread, it has a good picture showing the water pump numbers where the big hose that connects with the bottom radiator hose attaches to the water pump. https://classicoldsmobile.com/forums...4847-a-142161/
