Specs

I do know that for the IROC-Z series, from '87-'89 (I think), they put the 5.7L from the Corvette into the Camaros. I do not know about a 1991, although by this time just about all cars were fuel injected and cars were coming out of the fuel war between efficiency and gas mileage. Also power seats were available well before you car was made, even in Camaros, so the power seats are not necessarily N/A (not available), the person probably just didn't know whether or not these cars were able to be bought with power seats. It's a gorgeous Camaro though, I have a black '85 IROC-Z with the 5.0L High Output 4-barrel carb. Love it to death, but I would LOVE to drop your engine into my baby.

the iroc first became availble with the 350tpi in 1986 although they are extremely rare. then all the way through 92 the z28 camaro was available with 2 different 305 setups and the 350. the iroc was discontinued half way through 1990 but the z28 continued. it was also available with the same engine options as the iroc.

The 350 tpi technically wasn't a production engine in 1986. Only 50 were made for executives and such and was not an option. I'd like to see one though.

yes they did put a 350 in that type of comaro, its rare, any camaro like that with t tops will likely have a 305. irocs were mainly a 305 with a tricked out cam stock and later had tuned port, similar to a 91 vette. by the way your car is a rare sight, its not beatup like molst i've seen. not bad.

i had the 89 iroc with 350 tpi and t-tops. wish i never got rid of that car. came stock wirth 4 wheel disc brakes and oil cooler also. after the aftermarket parts i put in it, that car moved.
