Unless there is something besides all the parts taken off of it I will say that is too much, even by California standards. If the main bearing caps are missing, it is a boat anchor.
It's better to start with a complete engine, even if you don't use a lot of it. You have reference points for little things. And time and money spent chasing down little things like a cam thrust plate. Yes, they can be found. But you have to find one, buy it, wait for it. And if you had a whole engine to start with you would know that the thrust plate you have is going to work just fine. That's just one part. There will be a whole box of those little parts you will want as you put the engine back together.
