5.3L or5.7L Aluminum Build

I just picked up a 5.3L Aluminum Long block With 243 Heads,
I don't know what way Im going to go with this build.
So I am going to list it as a 5.3L first if I dont get any intrest, I will bore it out Put new LS6 Pistons in it and make a Gen 4 LS1. I am going to include the Harness Adaptors with this engine so you can bolt it in to any 97-current LS/Vortec application. The engine had 16k on it when it spun a Rod Bearing...(Picks of the spun bearing included below)

5.3L Aluminum Block light honed and ready to go with ARP head studs.
