    Does anyone know if you can or is it possible to bore a 6.2 block to 6.5 blocks dimensions? And then use the 6.5 pistions?

    The only 6.2L block that can be safely bored to a 6.5L bore is the 599-casting-number block. This is the "transition" block used by GM when they went from 6.2L to 6.5L. This block is essentially a 6.5L block that was only bored to 6.2L standards.

    The earlier 6.2L blocks don't have enough meat in the cylinders to allow them to bored that much.
