1990 Camaro Specifications

 Image: Auto Trader Classics

The 1990 model year marked the last year of the IROC-Z, with an available airbag and an upgrade from the base 173ci V6 to a new 191ci V6. Though still the same engine, the 350ci TPI engine saw an increase in power to 245hp.

Once again, the RPO 1LE code was available on IROC-Zs with the G92 Performance Axle Option without air conditioning, but much like the year prior, just 62 of these special performance cars were produced.
