the 350 in my truck was just recently rebuilt, 0.30 over pistons, .20 under crank, .488 lift comp cams cam, lifters and springs. The problem is that sometimes there is a noise that comes from inside the engine, sounds like something is rattling against one of the counterweights on the crankshaft, took the oil pan off and found the oil pump pickup laying on the bottom of the oil pan, so I put the pickup back on and then tack welded like it was suppose to be. But the rattle is still there, not all the time, just when it's cold or I turn a corner really fast. I can sometimes hear it when I crawl under the hood and rev the engine really hard. Could something be broke in the transmission making that sound or could it be my flywheel doing it. Already ruled out dipstick, checked the torque converter bolts, and the bellhousing bolts. Although the bellhousing bolts were a little loose.
