Go to FLAPS and buy some plastigage, it's only a couple buck and will tell you if you have the correct bearing clearance.

What are the measurements on the crank and the bearing?

If you tried the rod on all four journals and it is tight on all four, then it's either the side clearance or the large end needs the cap cut and resized.

X2, most likely the big end of the rod is out of round.
You are putting the cap on correctly with the bearing tangs facing each other correct? also the correct number match cap and rod.
I know silly question, but you never know.

You are torquing the bolts to spec on the rod prior to turning it correct?
The big end does not round out until torqued down.
