This sucks given all the work you put into your bike.  As the others said, you can swap just about any SOHC750 into that frame.  The 69-76 motors will require the least amount of compatibility issues.

Sorry to hear.   I'd look for a replacement engine, they can be found relatively cheap

I have a spare used head complete. Probably cheaper than an entire engine.

Hey y'all! I have a work van now (an E350 I nabbed for $100 because it had a differential oil seal leak, lol), and a line on a couple local, complete engines out of running bikes. I have the option of a 1976 K for $150 that's 45 miles from me, or a 1972 K for $200 that's 85 miles from me. Thoughts on which I should spring for to get this bike back on the road? Super Sport engines comparatively uncommon, it seems.

I can't think of any reason to spend $50 more dollars and drive 80 more round trip miles to get the K2 engine.

K2 tends to be worth a bit more.
 Ask questions about chain damage .. and try to inspect that area , and fin damage.
 And check around lower edge of point cover for damage or repair.

Not so bad if those gave been fixed properly  what you don't want us cases welded together.
 rear motor mount above chainare sometimes welded, and the main bearing bolt bosses just past the point area  those areas take the hit in bikes that get written off.
 And the wurst , oilfilter thread damage m but that is quite rare.
And often you see mismatched top ends.           Good luck

I will say the 76 is painted black (and that paint is peeling) despite being a K engine. It is whole with the oil tank and everything else though, whereas the 72 is totally disconnected and also has no starter cover.
