This is an estimate. The long block with the intake plenum, exhaust header, fuel rail, and accessories may even be near 300 pounds. (The 90 pound transmission stays.)
Upon removing the engine, I learned about the intermediate drive shaft.
The intermediate drive shaft connects the driver side axle shaft to the trans-axle which is on the passenger side of the engine bay. The intermediate drive shaft mounts on the transmission at one end and bolts to the engine block on the other. This is a bit of fabrication that I had not been thinking about.
