Documented applications

Custom Cruiser — B-body (1983–1990)

1983–1990 Single-source

Oldsmobile 307 V8; Wikipedia's Oldsmobile V8 engine article lists the LV2 (VIN code Y) for the Custom Cruiser through 1990, and its Custom Cruiser article names the 307 as the engine; no factory page prints the code for this car, so the row rests on those Wikipedia articles (one source, not independent of each other), and 1983 to 1986 and 1989 come from them alone; shared B-body code, cited from the Chevrolet Caprice kit (1987, 1988, 1990), where it is the Caprice wagon's engine; the Caprice kit pages are corroboration only

GM Heritage factory kit — 1987 Chevrolet Caprice, p.18.
GM Heritage factory kit — 1988 Chevrolet Caprice, p.14.
GM Heritage factory kit — 1990 Chevrolet Caprice, p.15.

Cutlass Supreme — G-body (1983–1988)

1983–1988 Single-source

optional engine through 1987 and the only engine in 1988; Wikipedia's Oldsmobile V8 article lists the Cutlass Supreme through 1987 and the Cutlass Supreme Classic for 1988; eightiescars.com prints LV2 for the 1985 coupe as a 140 horsepower option; no Monte Carlo kit offered this code

Delta 88 — B-body (1983–1985)

1983–1985 Single-source

Oldsmobile 307 Rocket V8; Wikipedia's Oldsmobile V8 article lists the LV2 (VIN code Y) for the Oldsmobile 88 for 1980–1985, and its Eighty-Eight article names the 307 as a 1983 option and the 1985 cars as the last with Rocket V8 power; 1984 from a 1984 Royale Brougham with the Olds 307 (The Truth About Cars); the Caprice kits of these years show the Chevrolet 305 (LG4) instead, so no factory page prints the code for this car

Ninety-Eight — C-body, rear-drive (1983–1984)

1983–1984 Single-source

the Oldsmobile 307 V8, VIN code Y; Wikipedia's Oldsmobile V8 article lists the LV2 for the Oldsmobile 98 through 1984, and its Ninety-Eight article gives the 307 V8 for the generation; shared C-body code, 1984 also cited from the Buick Electra block of gnttype.org's 1984 Buick VIN table, which prints the LV2 (T3, a sibling source that does not lift the row)

Toronado — E-body (1983–1985)

1983–1985 Single-source

the Oldsmobile 307 V8 (VIN code Y), standard in 1985 per Wikipedia's Toronado article; Wikipedia's Oldsmobile V8 engine article prints LV2 and lists the Toronado through 1985; shared E-body code, cited from the Buick Riviera: gnttype.org's 1984 Buick VIN table prints LV2 for the Riviera convertible, sibling corroboration of the code, T3, which does not lift the row; its 1983 table repeats the 1984 one and its 1985 Riviera block repeats a later model year's table (a different engine), so neither adds a year

This page aggregates every documented appearance of LV2 in the Oldsmobile reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
