Nice looking motor.

I recall building a Ford short block many years ago.
Which brings up one of my off the wall questions -

The crank was hard to turn, probably from incorrect ring or crank bearing sizes.

What is an acceptable crank 'hand-turned' torque on a rebuilt shortblock?

For instance - if it spins with a speed wrench - its too loose???
On the other hand 30 ft/lbs is probably too tight???

Thanks - Bert
