Happened to run across this, did a search and didn't see it posted here. Thought it might help others as it did myself. I was looking for info re Edelbrock 7111, Holley's etc
Just click on the alphabet to search for brand of part you're interested in. https://www.manualslib.com/brand/

 

Thanks for the link. This is a link to GM parts books that I've posted before but it's worth posting again. There are a couple of older Oldsmobile books there, a 1962 Parts Book, a 1965 Body Parts book and a Jan 1972 Parts book and Illustration Book. There are also 1980s books if you scroll further down that first link.
