Just some data points for comparison, since I'm doing a nearly identical rebuild.

- With just the crank installed, I could rotate it easily with essentially no effort.

- With the crank, pistons (new rings, fresh hone), and cam installed I can turn everything over easily with a standard 1/2" ratchet and socket on the cam nut. The resistance is variable, but easy to overcome. Before putting the oil pan on, I could turn it over by pulling on the crankshaft counterweights . . . harder to get moving, but once I was past the static friction and was just sliding it wasn't so bad.

- Have not installed the head or valve train yet (awaiting a head gasket) but can certainly slap the torque wrench on there and let you know what it takes to turn over.
