I highly doubt the Gen III/IV (LS) engines have an INTERFERENCE fit between the pistons and cylinders. The engine wouldn't run, especially when you account for thermal expansion.

The sleeves may be interference fit between with the block on aluminum engines but I doubt the pistons are interference fit with the sleeves/cylinder bores.
