you do know they're exactly the same right? Basically you just run f-body accessories. Comes down to if you want to / can source the accessories, and future plans.
Josey, the 5.3L is an iron block while the LS1 is an aluminum block, right? Looks like the weight penalty for the 5.3L is about 85-100 lbs or so. (This isn't the end of the world IMO.)
It looks like there were a couple of variations of the 5.3L that were aluminum, but those seem to be on the rare side.
