You've struck very lucky there Tom!
I'd remove the sump to see if the bottom end looks as clean and new, if so just measure the end-float on the crank and if it's within spec, call it good and rebuild it with some assembly lube.
You can still see the hone marks in the pots, the cam looks new (i hope you didn't mix any of the shims up), the valves are very clean (noting the difference between front and back pots) as are the pistons.
If i were you i'd have a word with Luke for an oil cooler from a 940, it fits between the filter and block and uses coolant to cool the oil. What you have there looks to be the marine version of the same.
