Since you are pulling the pistons out I would put in forged replacements. Not that expensive. And maybe forged rods? Also drill and tap the oil pan for turbo or SC oil return line before you put it back together.
With a turbo or SC you won't need a big cam. Might find a nice used one on LS1tech.
Per the local turbo guys the 5.3 is the best for boost because it has the thickest cylinder walls.
