Chevrolet Camaro Forum : “info on Z28 camero”

there were three engines optioned that year. 5.7L TPI(350), 5.0L TPI (305), and the 5.0L TBI (305) which was the base engine.

there are only 2 options for the 89 IROC Z/28 either one will be TPI but 305 or 350... throttle body was only available on base model Z/28 not the IROC....

nice of you to interject Craig, but GM lists 3 engine codes for the 89 IROC. Not sure where you are getting your information from.

i have a z28 but most of the time when i order things for it, it doesnt have the option for the Z28, only for and iroc.  so does that mean that its in iroc?

'89 was the only year that the IROC and Z28 were optioned the same. Badging was the only thing different.

ITs CAMARO NOT MERO
