Like you, I worry about the dry starts/runs this engine has seen.
The VVT/AFM LS engines have been a problem from the start, Oil consumption, Lifter failures, Timing chain tensioner failures (Causing bent pushrods) & AFM manifold screen clogging.
If you were to install a new engine, Buy a 2008 & up LS3 long block, All your accessories, Intake, Oil pan, & exhaust manifolds will bolt right on. The only thing that has to be done is some tuning to get rid of the VVT/AFM.
Speartech.com or PCMforless.com can handle a mail order tune.
A new GM LS3 long block runs $5047.97 (+$1200 core), Your L92 is a suitable core, $1000 to install, $300 for fluids/Gaskets/misc. $250 for a mail order tune.
Enjoy another 200,000 miles worry free.
