Engine diagram??

[LuckyRabbit4]

66 C10 with a straight 6 250 maybe? 230?

Looking for a parts diagram of the whole engine. Obviously I know what I'm looking at but looking for specific parts that may be missing or baffling. Every repair I make I find another things that has to be replaced or seriously cleaned.

Any help would be nice. Even someone who has the time to take a few photos of their own engine of the same size and make a list of everything would be amazing.

Thanks!
