Chevrolet upped their game in 1985 with the introduction of the Camaro IROC-Z. This car is a 1988 convertible IROC-Z located in Westfield, Massachusetts. It has 35,766 miles on the odometer and looks like a bone stock, unmolested example of a very nice IROC-Z in one of the most popular colors. It is listed here on Craigslist for an asking price of $25,950. The car was only listed two days ago. We appreciate Pat L. bringing it to our attention.
This low mileage IROC-Z looks stunning with the doors and doors open. The two engines available were both Tuned Port Injection. The 5.0 liter (305 cubic inch) V8 was rated at 220 horsepower for manual transmission cars and 195 horsepower for automatic transmission cars. The optional 5.7 liter (350 cubic inch) V8 engine was 230 horsepower. You have to look for an “8” in the VIN code to verify if the car is really a 5.7 liter equipped IROC-Z.
This car is equipped with an automatic transmission. The grey interior looks good with the bright red exterior. The car is said to be unmolested and still retains the factory radio. The gray carpeting seems to look brown compared to the rest of the interior in this car. This car is optioned with power windows, power locks and power mirrors, in addition to the ASC convertible top. My brother, Barry, had one of the first IROC-Z’s built in 1985. We drove it to California to Texas and it was a blast. His car had the LG4 305 cubic inch V8 engine (read: underpowered) but it had a 5 speed manual transmission which was fun.
With its 16 inch wheels and performance suspension, the IROC-Z was a popular car. In 1988, Chevrolet sold over 24,000 IROC-Z’s. A little known fact is that Chevrolet stopped offering the LT model Camaro and the Z-28 option. So the only Camaros available were the base Camaro or the IROC-Z. This car is offered at a fairly high price but, if a convertible top is your cup of tea, this low mileage beauty looks really nice.
annnnnd… it’s gone.
The 350 was not available in convertibles.
I remember some IROC Zs were transformed from coups to convertibles by an after-market company way back when. I didn’t realize that Chevy also made them. Did that option come later in the production run? Looks really nice.

You are right
Aftermarket did modify these but in 1987 , ASC. American sunroof corporation began converting for gm , the brand new firebirds and camaros with t-tops were shipped to asc
My brain is foggy but a few smaller organisations chopped from 1982 , one being NCE
Feel free to correct or add
How was the same motor a 25hp advantage in manual ?
The cam mostly, and associated changes to the fuel/spark curves. The manual cars got the same cam as the tpi 350, which was practically the same cam as in the Impala/Caprice LT1s a few years later.
The 305/auto cam, commonly referred to as the ‘peanut’ cam, had less than .400 lift and was a case study of GM wimp-ism, probably intended to help meet some sort of EPA objective or regulation. It made the 305 smooth, quiet and weak, like a trolling motor. It’s the kind of roller cam that you make an ashtray or a beer holder out of. The crappiness of this cam cannot be overstated.
BTW, the manual cars also got a double cat exhaust and usually better rear end gearing, so the difference in driving experience between manual and auto cars can be pretty huge.
