Chev has a law suit on their small blocks from piston slap. Take your vehicle to a real DEALER and have them check the recal against your VIN #. This is a big problem for Chevy... the pistons are cam ground (not round) and expand to a circle in the bore as she warms up. The noise I suspect you are hearing is the famous piston slap that these units are getting known for. Go on some Cheby forums and I am sure you will find discussions on this issue. Hope that helps you --
