I just purchase a 1951 Olds 88 Rocket. At some point the engine was rebuilt, and during that process the oil pressure line was removed and never reattached. Any idea where that port is located? The engine is a 303 V8. Thanks for any help in advance.

 

Google is your friend. I found this that may help you. First post mentions the back right side of the block.

It attaches on top of the oil filter adapter.
