As to the first question how far apart do you want to take the engine, if it was running when you started work. I’ve owned my HUP since 1979 and I’ve never had the engine apart or even removed the oil pan, old adage if ain’t broke don’t fix it. But as you have it out I’d at least pull the pans and side covers, cleaning the crud out and putting new gaskets and seals in is worth the effort. Beyond that it really is a question of how well did run before. If an engine particularly the dipper six’s has not been run in a while dropping the pan to clean the troughs out, they can get pretty crusty.

Regardless of little or how much you do to the engine remember to reprime the oil system be for you try and start the engine. Running the pump with a drill is the only way to get the troughs refilled once they are empty, they do not get any oil when you fill the engine through the top end.

Now as to color of the engine everybody seems to believe that the engine color was gray and there is a standard Chevy gray. My only problem with that is that none of my three CMPs had any evidence of gray paint on the engines. All three were (an are) painted black.
