71 Duster 360 turbo build

The engine bay is looking just a little bit cleaner at this point!

Also, traded some junk for a 360 magnum out of a 2000 ram which I plan to build. It’s a 53020006-360 block which has oil holes for shaft rockers.

Help Identifying this Block

So are ALL 53020006 blocks drilled for the oil holes?
