When did fuel injection start? 1985? When did the sheet metal end 1990? When did vortec come into the picture?, 1996?? One last one, did the non-vortec-injected 454's, run better or worse than the vortec ones? I'm about to pull the trigger on a 1988 that's injected and pre vortec, my buddy says there gutless badddd. edit; my bad... I guess those aren't all square questions....
1987, 1991, Yes, TBI's make less power than Vortecs.
