The 1989 Allante had a 273 cid motor. The same engine that was in every other Caddy at the time. They switched to Northstar on the Allante in 1991, and brought it out on the rest of the Caddys in 1992. Neither the old 4.5 liter, nor the Northstar engine ever had variable valve timming. Even to this day, not a single Caddy has had VVT.
