Lemme toss a small wrench into the discussion. Speaking from a displacement perspective, there's enough meat on the 5.3 to punch it out to the much revered 5.7(346 ci). So upon a rebuild everything's there to work with. Infact that's my plan- when the time comes to drill it out .060", yes I know it won't be the 5.7 sought after but there will be enough meat for another rebuild after that............

I plan on doing a forged alum block LS1 to keep the mp112 in it's efficiency range.
