Park Avenue — C-body (1991–1996)

1995–1996 Single-source

the naturally aspirated Series II, 205 hp, replacing L27 for 1995; both years from Wikipedia's Park Avenue infobox, and its Buick V6 article gives the Park Avenue the L36 from 1995; shared C-body engine: the Oldsmobile 98 article's infobox and the V6 article's 1995–1996 Ninety Eight entry name it for the sibling, but both are Wikipedia, so the row stays single-source; the description follows the merged regal-w-body-1988 doc

Park Avenue — G-body (1997–2005)

1998–2005 Factory-verified

The 2003 list reads sequential fuel injection (SFI); the other lists, and GM's other lists, read multiport. NICB 1997 p.33-34 shows the Park Avenue with the 3.8L V6 MFI for 1997, which no archive list covers.

Regal — W-body (1988–1996)

1996 Single-source

205 hp; Wikipedia's Regal engine list gives L36 for 1996, and its Buick V6 article gives the Regal the L36 from 1996; the merged regal-w-body-1997 doc reads L36 from GM's 1998–2004 lists as a 3.8 liter multiport fuel injection, high output V6

Regal — W-body (1997–2004)

1998–2004 Factory-verified

Wikipedia gives the 3.8L L36 to the 1997–2004 Regal; the 2003 list reads sequential fuel injection; shared W-body code, Chevrolet Lumina kit (page prints the code beside the 3.8L engine)
