You'll find bearing material in the oil during the break in period, espeacially the first oil change. Keep an eye on the oil pressure and monitor your oil changes during the break in of the motor.

+1 on this one. I helped my buddy build a motor for my old car to learn the tricks of the trade and got the same thing. He told me that was normal and just to watch my oil pressure. You will probably see more of this during the break in but it should become less and less. Now onto why you would sell it. Was the motor professionally built ? If so did you get any kind of warranty ? The reason I ask is when I did my 406 sbc the stock crank was cut .010 under and there was porosity on rod journal #7. I took it back to the speed shop and he took it back to the crank grinder he uses. They took it .040 under and it was still there but the grinder swore I wouldn't have any problems with it and guaranteed it would hold up and not wipe out any bearings. At 2,8xx miles I had to pull the motor because it did just that and wiped out the cam and had some collapsed lifters as well. If I would have chosen to the speed shop was willing to replace all the bad parts that were bought new and in good shape such as my cam, bearings and so on.
