Do not bore the engine, just lengthen the stroke if you have the money. You will gain torque, and it will not increase emissions. That is what I have found out through reading or add a Magna charger, depends on your wallet.

Block should be fine, heads may be too.

If I were you, I would try to locate a 6.0 or 6.2 to start with. They both have the same heads (2007+ engines) and are some of the best flowing heads GM has ever released.

In pure stock form, both of these engines are capable of 400+ hp with just a tune. Do a search on this forum, a few months ago a cam was posted that added almost 60 hp to the 6.2.
