There were no IROC Camaros in 1991
No, some IROC's are a 305 5.0 Liter and have a 5 speed manual. Total production for IROC's in 1987 was 38889, 12105 of those were 5.7L IROC's. ALL 5.7L IROC's were 700R4 Automatics, the remaining 26784 5.0L IROC's were available in Auto or Manual Transmissions.
It's an IROC Z28. They are the same thing. they were the same in between 86-69(not positive on those years). iroc stands for international race of champions. once the license to use the name expired, the iroc z28 returned to just z28.
No GM did not start putting roller cams in the small block Chevy until 1987. The easiest way to tell is by looking at the valve cover although not always a definitive answer since you can swap heads or even get an adapter. If it has center bolt valve covers it is most likely from an 87 and later GM car or truck and would have a roller cam.
