The LS2 90mm intake manifold will bolt straight on.....however it flows no better than a LS6 intake on a stock cube LS1. Unless you got a totally wild H&C LS1 or larger than 383cuin its not worth the drama.
LS2 90mm TB is Fly by wire....so no throttle cable. You'll need a FBW loud pedal and harness. FBW Connectors are different to C5 vette so you still need to adapt wires even if you got an older FBW loud pedal.
Or you could ditch the 90mm FBW TB and bolt a 4bolt 90mm TB with throttle cable onto the LS2 intake.
LS2 Injectors are shorter (32.5lb/hr) and have different electrical connectors than LS1. So you need the LS2 fuel rail and 8 small adapter harnesses.
