1985 represented the return of
true performance to the Camaro lineup with the addition of the new IROC-Z. Named
after the famous racing series, the IROC-Z sported stylish 16" wheels
(still a popular bolt-on for many GM cars today) with P245/50VR16 Goodyear
Gatorback rubber. The 1985 production year also saw the introduction of the
famed TPI (Tuned Port Injection) V-8. The F-body version was 5.0 litre fare,
with engine code LB9 and making 215 horsepower. Unfortunately, this power plant
was only offered with the 700R-4 automatic and not the Borg-Warner standard.
The IROC-Z featured a revised front nosepiece and could be had with any of the
V-8's offered. Only the carbureted V-8s were available with the Borg-Warner
5-speed. The base Z28 was also offered with the TPI V-8, with a new trim
featuring louvered hood scoops. The Berlinetta and base Camaro were still
available, unchanged from before.
