Frankly, I had hoped for more responses, but since I didn't get those, I played it save and opened the engine, oil pan off first. With the spark plugs still in the head, the loss of compression trough the piston rings was clearly to be heard. Like an air pump. Puffffffffff.

We then removed one rod bearing, and it had the following number:

10 86 01C
CB 734 P

Well, was the 01C perhaps an 010 indicating oversize? (This is a real question.)

We then took off one main bearing, the one in the center, and it was clearly stamped 0.10

Camshaft looks like new on all lobes; cam gear is "like new" steel for the crank and fiber for the camshaft.

All pistons were stamped 0.40!

Still honing marks in the cylinder walls.

So while the engine may have been in a 1967 Volvo, it's hard to believe that this Volvo has been a low mileage car. Why would a rebuilt engine with new cam, 0.40 pistons, and bored crank be in a low mileage car, I wonder?

Final question: how do I identify what head I have? I want to have it checked for hardened valve seals and a 3-angle valve job performed. If it's a high performance head, all the better.

Thanks!
