Yep, something's not right. Metal from the bearings would be copper; you'd also have it in the oil filter - cut it apart to check. With a standard volume pump you should have 10 psi per 1000 rpm. With a high pressure, it should be 15psi per 1000 rpm. I'd be worried with on 19psi at idle. Sitting for a year shouldn't of been a problem unless the oil had water in it when it was put away. I'd check the block over to make sure its not cracked somewhere. #2 main web is probably the most common place for it to crack, starting at the cylinder bore to web line and moving towards the cam bearing. #1 main would be the next most common place. Sometimes you have to look really good to see the cracks as they'll follow the natural casting lines. You could also pop off #5 main cap for a quick look at the bearings. It usually takes the most abuse due to the 50 in-oz balance.

The motor would still be balanced just fine if you replaced the bearings. In the DSS blueprint sheet, what was the main journal clearance? It should only be about 0.0025".
