Custom Cruiser — B-body (1983–1990)

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

350 cu in; Wikipedia's Oldsmobile Diesel engine article lists the LF9 for the Custom Cruiser through 1985, and its Custom Cruiser article names the LF9 diesel as an option through 1985; shared B-body code, cited from the Chevrolet Caprice kit (1983 and 1985 engine pages; the 1984 page names the diesel only in a battery remark, which dates nothing, so 1984 rests on Wikipedia)

shared B-body code, cited from the Chevrolet Caprice kit; matched to the Custom Cruiser by meaning only: Wikipedia's Custom Cruiser article names the THM 200-4R 4 speed overdrive automatic through 1990 but prints no code, and the kit prints MX0 (the 1984, 1986, 1987 and 1988 pages print MXO) for the Caprice wagon among other models; 1983 is left out because the 1983 Caprice kit shows the overdrive automatic without a code, and 1989 because the 1989 kit's listed pages do not print it
