    Grand Am — N-body (1985–1991)
    • 1985–1987 Single-source

      optional Buick V6, 125 hp, with the automatic transmission only; Wikipedia's Grand Am article prints LN7 in its infobox and dates the engine from 1985 to its mid-year discontinuation; its Buick V6 engine article lists the Grand Am for 1985–1987 and gives the VIN letter (not independent); it was the SE's standard engine when the SE arrived

    This page aggregates every documented appearance of LN7 in the Pontiac reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
