If you have a real rod bearing issue, replace the rod bearings and put it back together. If you have a main bearing issue, pull the motor (though rolling a bearing is likely feasible).

If your oil pump is not producing good hot pressure replace it but I would suggest just replacing the pump pickup o-ring otherwise.

In an early post (like your last one) you were willing to scrap the car for requiring over-sized bearings (which cost the same as regular bearings)...so I am going on the assumption this car is of little value to you.
