My machine shop guy told me that a newly rebuilt engine (flathead 6) should turn over by hand with 35 ft lb on torque wrench. I was glad to hear it. I thought mine seemed tight, but it turns over with less than 30 ft lb. (I had to go buy a 1 3/4 socket to try this).

Was this before the initial run-in or after? I'm assuming w/o plugs

The tip I got from a very reputable machine shop here in San Angelo, Tx was that a newly rebuilt engine should turn over with 35 or less ft lbs. This is without spark plugs and before initial start up. After first start up and when engine oil has circulated, and engine is warm, it should turn with considerably less effort. I don't know where he got the number; probably from many years of experience.
