My Uncle showed up with machined engine parts for a 235 chevy engine, Crank, Cam, Block, Heads, and then some. "It just needs to be put together", he says.

Well the Crank Cam and block is coverd in rust, no major damage from what I can tell. I can hone out the Block and the head is good.
Can these parts be used as is after wiping them down with an oily rag? What is a good way to clean the Crank and Cam? They have been already machined. I did not want to use emery cloth or sandpaper. What should I look for in damage to the crank and cam?

Know where I can get engine rebuild manuel on a 1960 - 70 6 cylinder engine?

Thanks for the Info?
