| LF9 | Engine, 5.7L V8 diesel, Oldsmobile | 1983–1985 | Wikipedia's Seville article lists the LF9 diesel V8 through 1985, so the whole span is dated by that one line; the NICB 1983 and 1984 Cadillac VIN tables print a 5.7L V8 diesel engine symbol but no RPO code, so they do not name the code; Wikipedia's article for the nameplate is one source | Single-source |
| LT8 | Engine, 4.1L V8, HT-4100 | 1983–1985 | Wikipedia's Seville article lists the LT8 HT4100 V8 through 1985 (135 horsepower), and its Cadillac High Technology engine article calls LT8 the HT-4100 option code and lists the Seville (the same source family, not independent); the NICB 1983 and 1984 Cadillac VIN tables print a 4.1L V8 DFI engine symbol without a code; no Seville-specific source prints the code | Single-source |
