Good points...
The valve covers are on the wrong sides. The one with the tabs for the electrical wires goes on the passenger side for the harness that goes from the firewall to the alternator and horns. Those valve covers are from a 67-68...
That vibration damper and pulley look funny coming out of the front of the engine - something doesn't look right. I would need to see a better picture of it from the side in a closer view to see what's going on.
I agree that it should be looked at before installing in a car... Are the pistons in correctly or backwards if he got the valve covers and oil pan backwards???
The front of the engine is set up for a 64 - 69 vintage car. There are no timing marks on the timing chain cover, you will need to get a timing tab from a 64 - 68 small block that bolts onto the two lower water pump bolts. 69 had the marks cast into the timing cover. In 70 the marks changed sides.
If you want to install this in a 70 and later car, I would replace the timing chain cover and water pump to the later style with the timing marks on the opposite side and aluminum water pump.
Here's where he can get a new crank bolt and washer:
Mopar Performance Crank Bolt, 2.25" Long
It's a nice engine, just make sure it's right before you install it....
