stock ls3 vs. a ls9 w/ no charger?

[454lsxss]

So what is the big difference between these two motors besides the obvious supercharger? I guess maybe the internals are forged, but how far did they take it? I guess maybe i'm saying what would be cheaper; a ls3 turned into a replica "ls9" with similar parts and same supercharger, or a ls9 crate motor swap? I think it's cool the ls9 is going to be crate, but wouldn't a simple Eaton twin screw or something like it put out the same numbers for a huge price difference? Could someone fill me in?

well the ls9 has titanium rods, forged dished pistons, oil squirters, 12mm head bolts instead of 11mm, thicker head gaskets, and i think thats about all the major points. If i missed anything guys just fill them in

even so, wouldn't all those mods still be cheaper than a crate motor + the extras to get it running in your 'maro?

I would guess yes as you wouldn't have to buy everything ..

Does anyone know how close the internals are between the LS3 and the LSX?

the ls9 has piston oil squirters

titanium and sodium filled valves

forged aluminum pistons

titanium connecting rods

special casting special alloy heads
