Scored Main Cap Bearing - Ouch

Ok guys heres an update. Against my own advise I decided to finish the work on installing the bearings and getting thr mtr to run again. John dont be to hard on me. LOL Since I already had the bearings, rear seal and pan gasket I went ahead and finished with the assy under the car. Everything back together and went for a 50 mile drive yesterday. Oil pressure was 70 cold and settled at 65 hot on the highway at 2600 RPMs and 170F water. Pulled the oil filter today and tore it apart and found only 1 tiny fragment that would not pass through the element. Drained the oil and it is contaminated with bearing metallics, but not like the concentration before. I am hoping this is left over and the flush will catch the rest. Filter doesn't catch any of these particles. Im running 10/40 and Lucas additive. Have kept RPMs under 3500 and easy driving. So where do I go from here. Frequent oil changes and filter checks? At what frequency? How should I drive it, rings are seated.
I would also like to thank everyone for their advice given and for being a part of the thread. I will continue to post updates when they happen. Hopefully they will all be good. FOR THE GOOD NEWS THE REAR SEAL LEAK THAT STARTED THIS ADVENTURE IS NOW FIXED. NOT A DROP.
Should have fired it up, idled it for a couple min...then drained the oil, not drive it 50 miles. That way.. if it is left over, you get it to the pan and drained, not cycle it through bearings for 50 miles.
I failed you... in that I didn't tell you that.
I did not think you would go drive around on the first oil change. You gotta treat it just like a cam break in, change the oil AND filter before you go driving it.
Some people leave the filter on for the 1st 2 changes, no thanks.
