check the table at the bottom, there was never a factory TBI V6 in a camaro, only the carb'd 2.8 from 82-84 and the MPFI 2.8 from 85-89...

true, but seeing how this is a 60*V6 site, i didn't feel the need to mention other motor families...

S-10's were Carb'd until 85 then they got TBI until 1992 when the 4.3L CPI (RPO W) engine was introduced. But the 4.3L TBI motor was still available until 1995 and that is when TBI ended production in all vehicles. In 96 TBI was no longer around. The 2.8L and 2.5L TBI engines ended in 1993. The GMC Syclone/Typhoon was the only 4.3L to receive SFI, With injectors attached to fuel rails. All other 4.3L engines to this day are CSFI which has injectors attached to fuel hoses which come out of a fuel pressure regulator

The Camaro went from carb right to MPFI in 85. In 1993 it was upgraded to SFI on the 3.4L. The Camaro had iron heads on all its V6's until it ended production
