The Motion car pictured is definitely an 82-24 model, and based on a Z/28, not an Iroc-Z. The Iroc-Z was introduced for the 1985 model year, and was the first camaro to offer 16" wheels. Originally they were only offered with a 305 V8, either carburated or with TPI as an option A 5.7 Liter TPI 350 was offered beginning late in 1986, but only with an auto tranny. 1990 was the last year for the Iroc. The Z28 replaced it in 1991, and was the "top dog" in the Camaro linup once again, until the introduction of the SS model in 1996, in conjuntion with SLP.
