It was just an incorporation of the "Z" in Z-28. IROC stood for International Race Of Champions.....from the Nascar IROC races.
no, all IROC-Z's were V8s.
the last production year for the iroc z was 1990, there is no such thing as a 1991 iroc z
At the end of its production run, Iroc z numbers had totalled 170,000.
no

Beverly Hills Cop II with Eddie Murphy. A black IROC-Z I believe with T-panels.
The 1989 Chevrolet Camaro IROC-Z (RPO Code 1FP87) was built in a coupe and convertible options. The available powertrains for the IROC-Z were the LO3, LB9, and L98 8-cylinder engines with 5-speed manual or 4-speed automatic transmissions. 20,067 IROC-Z coupes and 3.245 convertibles were built that year.
there was no 91 iroc-z the very very very begging of the 1990 model camaros were iroc-z this is because it they were still in the 89 yr and they were producing 90's. and December 89 was the last yr of Chevy's iroc contract. then it was on for the dodge daytonas. so u most likely have a z28 if ur thinking its an iroc-z. u might have the graphics but there are plenty of clones around **** The above answer is partially correct but answerer needs to learn how to speak proper English and spell. I can't understand any of what he said and I'm not sure how the questioner could either. My answer is that there are NO 1991 or 1992 IROC-Z Camaro's. 12/31/1989 was the last date of production for IROC-Z Camaro's as GM lost the rights to use the IROC-Z namesake on the Camaro to the Dodge Daytona. There were a very limited number of 1990 IROC-Z Camaro's produced. The horsepower rating for a 1991 Camaro Z28 350 is 245hp. If anyone tells you that they have a 1991 IROC-Z Camaro then they're lying to you. ****
Chevy never made a 1986 IROC-Z convertible, not till '87 - so the answer is no.
in the glove box mine is in the center between back of windows switches 1988 iroc z
No they are not. Base engine on an '88 IROC was a 170 hp 305 TBI.
