Which engine route?!
so far in this thread the original poster has not mentioned the word budget or how much is in his budget.
My 5.3L leaks/burns nearly 2 quarts of oil per oil change interval. Also has piston slap when cold.
Best motor ever built to date.
I don't know where you're getting your info from, but its wrong.
It doesn't take a genius to look at the differences in the engines and understand that aluminum/neoprene gaskets seal better than shitty old paper ones, and a flat plane cast aluminum oil pan with an aluminum gasket seals better than a piece of **** stamped steel one with a cork gasket and crappy rubber end seals with RTV. Use some common sense, you're sounding very ignorant.
Sounds like your problem. Leaks are not common on these engines.
LS engine have some of the best engine sealing in the industry. The oil consumption is from the PCV, which you obviously do not understand. The piston slap is a known issue on older model engines, but is not detrimental to performance, fuel economy, or engine life.
