He used the keyway to align the bottom sprocket with the top instead of using the "Zero" "dot" on the sprocket. The keyway should be pointed to about 1:30 oclock.

The 0/keyway is lining up with the alignment dot on the cam gear. There should be a corresponding dot on the crank gear that lines up with the dot on the timing gear for 0/straight up.
They way was installed, the cam was very advanced leading to intake valves smacking pistons.
Could have been a lot worse.
Dave, make sure to get the intake valves checked. It was pretty noise when running and pictures make it look like they were all touching.
**Edit - I saw you mentioned above that you had new valves.

There are dots on the timing gears that need to be aligned, not the Zero at the keyway.

Edit: rookie, you're right, but here is how I set it up on my 69 which is the correct way. What's missing is the printed zero that lines up with the upper dot on my boat 454.
So it's my fault in that I didn't notice the marks were missing and I lined it up with the wrong 0.
