tirefryins10 claims, if I understood his Mustang thread correctly, to have gotten his Mustang into the high 9s with used stock 5.3 truck block, crank, rods, pistons, pins, rings, bearings and heads. If he NEVER had ANY detonation, then it seems plausible to me. You should shoot him a PM.

I had a 5.3 for 3 years untouched shortblock w/ 100k+ miles on it. (317 heads and bigger cam) It made 640whp on 15psi and a 50 shot of N2O. 93 octane. I finally spun a rod bearing... stock ones apear to be to soft aluminum. But it was reliable for 3 years, and the rest of the inside looks perfect.
I had a really crappy inefficient converter... im sure the engine produced over 700hp.
Id use all stock parts... maybe swap out the bearings.
thats my experience..
