Here is the IMSB with the outer seal removed, closer inspection has not turned up any anomalies so it is staying put.
I inspected the cylinders with my borescope and all looks good.
The spark plug tubes are not leaking... so I assume the orings have been changed at some point.
Checked the accessories and pulleys at the front of the engine and all turn easily with no looseness. I think I will leave the alternator, power steering pump and starter that came on the engine rather than transferring over those that are on the engine that is in the car.
I have pretty well decided to install the engine as is and run it this summer while working on the original engine.
I have ordered a new AOS, pilot bearing for the flywheel and a clutch throwout bearing as well as a new engine mount and various gaskets and fasteners.
Here is the engine mount that came with the engine... the mount currently in the car is also shot.
