They had both the 305 and 350 in 1990. In 1993 with the release of the LT-1, the 305 option was deleted.
All the 1993-1996/1997's featured the LT-1 rated at between 275-285hp, 305 for the SS and WS6. The 1997/1998-current models got the new LS-1 underrated at 305hp, 320 for the SS and WS6.
Most of the 1984-1992 Z28's got the 305, some got the 350. Same with the Trans Am's I believe.
