Roadmaster — B-body (1991–1996)

170 hp; the standard engine of the 1991 car, the Estate Wagon only; Wikipedia's Roadmaster article names L03 and dates it 1991; shared B-body code; Wikipedia's Oldsmobile Custom Cruiser article (the B-body wagon sibling) also names the L03 and dates the 5.0L 1991, but as a second Wikipedia article it is not counted as an independent source; the Chevrolet Caprice kit's 1991 specification pages (pp.6 and 45) print LO3 but no readable model year (the p.45 year field prints only the issue date 12-89), so they date no year and are not cited

180 hp, sedan and wagon; Wikipedia's Roadmaster article names L05 as the L03's replacement for 1992, until the LT1 of 1994; Wikipedia's Oldsmobile Custom Cruiser article (the B-body wagon sibling) dates the L05 1992; shared B-body code; cited from the Chevrolet Caprice kit: the MVMA specification pages for model years 1992 (power team D, printed LO5, the police 9C1 sedan, and the police-sedan engine page) and 1993 (power teams, LO5), and the 1993 order-guide power teams; 1993 p.22's fourth column prints LOS (an S for the 5), which is not read

260 hp, sedan and wagon; Wikipedia's Roadmaster article names LT1 from 1994 and its OBD-II change for 1996; shared B-body code; cited from the Chevrolet Caprice kit

the hydraulically controlled 4L60 (700R4) behind every engine, replaced for 1994 (Wikipedia's Roadmaster article, which prints no code); the code is from Wikipedia's 4L60-E article, which names the 4L60 as RPO MD8; shared B-body code; cited from the Chevrolet Caprice kit, whose MVMA specification power teams print MD8 for model years 1992 and 1993; 1991 rests on Wikipedia alone, because the kit's 1991 power-team page (p.45) prints MD8 with no readable model year, so the row is single-source; GM's later lists reuse MD8 for a 4L70-E

the electronically controlled 4L60-E; Wikipedia's 4L60-E article names it RPO M30 and lists the Roadmaster for 1994–1996, which dates every year; shared B-body code; cited from the Chevrolet Caprice kit's MVMA specification pages for model years 1994 (the LT1 engine page), 1995 and 1996 (power teams, M30 with the LT1); the 1994 pages whose year field reads '•394' or '*394' (pp.37, 57) are not cited

the order code the Caprice order guides print for the four-speed automatic, matched to the Roadmaster's unit by meaning: no Roadmaster source prints MX0; the pages print MXO; the 1993 order guide prints MXO for the power teams the 1993 specification page codes MD8, and the 1994–1996 guides for those the specification pages code M30, the pages not saying whether the codes are one unit; 1991–1992 are left out because no kit page with a printed model year prints it (the 1991 specification page prints MXO and no model year); shared B-body code; cited from the Chevrolet Caprice kit
