How difficult is it to turn an engine by hand?

Did you measure your bearing clearances? What are they?

As you install each piston, there is more drag. Usually by #5 or #6, it becomes difficult.

I personally didn't measure the bearing clearance but my grandpa did and said they were all good, the machinist that worked on the engine has worked on many of my uncles and grandpas engines, and everytime they checked over his work it was perfect, expensive as hell but does very good work. So I'm not worried about incorrect bearing clearances, I'm more worried about something not being lined when the bearings were installed. How hard is it for a bearing to no seat properly?

And yeah that sounds about right, after about 5 pistons I had to try a bit harder to turn the motor over.
