📖Generation guide
IROC-Z • 1985-1987
This generation features the 305 LB9 TPI engine and the 350 TPI variant in 1987. Notable for its performance, it includes both hardtop and convertible models, with the convertible being a sought-after halo trim.
IROC-Z • 1988-1990
The final IROC years maintained the 305 TPI standard engine, with a 350 TPI option becoming available. Unique offerings such as the 1G1FP IROC convertible and the B4C Police Package highlight this period's performance focus.
Z28 • 1991-1992
Post-IROC, this generation retained the performance legacy with the B4C 1LE option continuing. The 25th Anniversary model in 1992 is a collector favorite, marking the end of the third-generation F-body.
Known issues by generation
Across the IROC-Z and Z28 generations, common issues include TPI distributor and ignition module failures, which can be attributed to the age of the HEI distributor. Additionally, the infamous 700R4 transmission often exhibits overdrive failure, particularly with the 3-4 shift solenoid. T-top models frequently suffer from water leaks, necessitating intensive gasket replacements, while dashboard cracking is commonly found in sun-exposed examples. The original paint and clearcoat deteriorate, particularly in the models from the single-stage paint era, leading to severe oxidation. For collectors, maintaining an original-paint vehicle is key to preserving value, especially as original examples continue to appreciate.
Donation value by condition + generation
The value of your Camaro IROC-Z or Z28 can vary significantly based on condition, originality, and documentation. Cars with original paint and those that are numbers-matching are experiencing the fastest appreciation, as noted by resources such as Hagerty Valuation Tool and Sports Car Market guides. Comps from auction sites like Bring a Trailer and Mecum showcase how premium examples—especially those with documented build-sheets—command higher values. Additionally, there's a notable differential between T-top and coupe models, with coupes often fetching 20-30% more due to structural integrity and leak history.
