Larry didnt have a clue where that alum came from and I really dont know either.... it was in the pan and the filter so it had to start from in the pan but it was in the bearings also... so that would mean it was in the oil gallies also or it got through the filter(which I doubt).... I cleaned that block 3 times before I started assembly so I dont know... looks like I'll order up new main and rod bearings and do a hone then clean it AGAIN and try 1 last time... I think I'll pull the heads apart to check them real close and clean them... thats all I can think of... I have 2 more 340 blocks that are bored but I would have to have either of them decked to my set up but that will be my last resort.... still think I should have done a WOT run.... that would have found the problem
