Silhouette — U-body (1990–1996)

1996 Single-source

the only engine for 1996 per Wikipedia's Silhouette article (first-generation infobox and 1996 section), which is the only source cited; no listed kit page for 1996 prints the code, so the row is single-source; the Chevrolet Lumina APV doc gives sequential fuel injection from a 1996 power teams page not cited here; shared U-body code

Silhouette — U-body second generation (1997–2004)

1998–2004 Factory-verified

the 2003–2004 lists read sequential fuel injection
