I would assume it would be the LS7, which you are correct in saying it is a 427. a 454 is a BB motor. All LSX motors are SB's.
LSA is essentially an LS9 with a smaller supercharger, outputs round 550+hp if i recall.
i'd say LS7 is going in, LS9 is ZR1 territory, i don't think that's where the Z28 needs to stand. maybe an LSA could go, but my guess is the LS7.
