I am buying a 1987 Camaro with 350 5.7L engine Is it an IROC or Z28?
A 1987 Camaro with a 350 (5.7L) engine could be *either* an IROC-Z or a Z28. The 350 was a common engine option for both models that year. You'll need to check the vehicle's identification number (VIN) and/or the trim tag (usually located in the driver's side doorjamb) to determine the exact model. The trim tag will clearly state whether it's an IROC-Z or a Z28.
