Engine build pistons
I have a set of pistons i want to replace the factory with some forged pistons, has anyone ever done any build with the wiseco pistons and if so do you know if an 09 hhr ss has rod bushing and or rod bearings?

Pins I believe..when they did the first "lets see how much power we can make on a stock block" test runs they got up to just below 750hp , a galling P-Pin was the problem. Up to this point they did nothing to the internals...
