Now what?

[kmcnelis@nmsu.edu]

Put the crank back in, new main bearings, no problems. New pistons & rings, 
not problems.  Put the rod bearings in, no problem.  Tightened the rod bolts 
to spec-  big problem.  Crank absolutlely will not turn.  Loosen the rod bold, 
crank turns with little effort.  Retitghted bolts to 20 lbs, can turn the 
crank with a lot of effort.  Tighten to 40 lbs-  no way to turn the crank. Did 
not have the cranck machined, old rod bearings were +.020.  Replaced 'em with 
+.020.

HELP!
