Re: 305K GM Engine
Lisa, I'm sure that one of the CC guys will chime in with a link to a manual for you.
Meanwhile, just was is it that you need re; the 305K engine?
Some engine related questions do not necessarily relate to Chris Craft alone.
Side note: here is what MM shows for a replacement 305K engine... but is much later than 1982.

BTW, if having one built, the 5.7L can usually be built for less than the cost of building a 5.0L.
(305K = 5.0L)
