Engine, 3.4L V6, DOHC, multiport fuel injection

the GTP's engine from 1991, 210 hp with the 5 speed manual (Wikipedia); from 1994 in the GT and GTP packages; Wikipedia's Grand Prix infobox prints LQ1 and its 60° V6 article lists the Grand Prix under LQ1 for 1991–1996; the 60° V6 article dates sequential port injection from 1994, and the 1995 Monte Carlo order guide words the engine 3.4 liter SFI V6, while the 1994–1996 weight pages still write MFI; 1994–1996 stand although Wikipedia puts the 3.4L inside the GT and GTP packages, because the 60° V6 article lists the Grand Prix itself as an LQ1 application for 1991–1996 and every cited kit page prints LQ1 as an engine line of its own, not as package contents; shared W-body code; cited from the Chevrolet Lumina kit (1991, 1993, 1994, 1996) and the Chevrolet Monte Carlo kit (1995)
