    Skyhawk — J-body (1982–1989)
    • 1987 Confirmed

      165 hp; Wikipedia's Skyhawk and Family II engine articles give it to the Skyhawk for 1987 only; gnttype.org's 1987 Buick VIN table prints it for the Skyhawk (a second source (owner ruling, 2026-11-05: a T3 page that names the code for the Skyhawk, with Wikipedia dating every year))

    This page aggregates every documented appearance of LT3 in the Buick reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
