Piston slap is not a major issue as long as it goes away once the engine is warmed up.

This is a known LS1 issue:
http://en.wikipedia.org/wiki/Gm_ls_engine#Problems
Problems In the early production run of the LS-series engine, some engines encountered abnormal amounts of 'piston slap' - a problem caused by too much clearance between the cylinder bore and the piston. [11] 'Piston Slap' sometimes sounds more like a knock or the sound of a diesel engine running, it is also typically worse when the engine is cold and lessens as the engine reaches operating temperature. The noise of 'Piston Slap' often is louder when listening for it below the oil pan.

I am really suprised there has not been a class-action lawsuit against GM for this defect?!
