1985 Model Year

Total Production 21,177
IROC-Z Option Code B4Z
Base Engine LG4 "Quadrajet" Carbureted 305 CID (5.0L) V-8
Optional Engine(s) L69 "Quadrajet" Carbureted H.O. 305 CID (5.0L) V-8 LB9 Tuned Port Injection (TPI) 305 CID (5.0L) V-8
The IROC (International Race Of Champions) began using the Camaro as the official vehicle. To commemorate this, Chevy made an IROC model for the Camaro. The IROC-Z was option B4Z on the option sheet and could only be ordered with the Z28 option package. The ride height was lower than a standard Z-28, and featured performance-calibrated front struts and springs, Bilstein rear shocks and 16 inch aluminum wheels with Goodyear Eagle 245/50/16 tires.
This new performance icon boasted skidpad numbers within the range of .90 g. The top offering under the hood was the brand new TPI 305 (LB9) which boasted 215 horsepower and 275 ft/lbs of torque. Recipients of this engine wore the badge. This was the most powerful 305 automatic ever offered in the IROC. The 190 horsepower HO 4bbl 305 and the standard output 155 horse LG4 were the other available motors.
The IROC also came with a redesigned front fascia with a more rounded appearance and a deeper chin spoiler with lower ground effects. The new fake hood louvers were introduced on the Z28 and IROC. The IROC was available in Yellow, Bright Blue Metallic, Black, Silver Metallic and Red.
*A ‘unique’ feature of the 1985 IROC-Z, is that there is no third brake light. Neither near the top of the hatch window, nor in the rear spoiler.
*Colors available were White, Black, Bright Red, Yellow Gold, Bright Blue and Silver. 1985 was the only model year you could get a Silver IROC-Z.
*All 1985 IROC-Zs have the 85MPH speedometer, regardless of engine or transmission option.
*The 5000 RPM redline tachometer was used on LG4/L69 (305 CID "Quadrajet" Carbureted) equipped 1985 IROC-Zs, regardless of transmission.
*The 5500 RPM redline tachometer was used on LB9 (305 Tuned Port Injection) equipped 1985 IROC-Zs, regardless of transmission.
*16" aluminum wheels with the single (wider) line through each spoke as standard on all 1985 IROC-Zs.

1986 Model Year

Total Production 49,585
IROC-Z Option Code B4Z
Base Engine LG4 "Quadrajet" Carbureted 305 CID (5.0L) V-8
Optional Engine(s) L69 "Quadrajet" Carbureted H.O. 305 CID (5.0L) V-8 LB9 Tuned Port Injection (TPI) 305 CID (5.0L) V-8

In 1986, the IROC received slightly different engine packages. The 86 IROC is the armpit of the entire run. The 305 block in 1986 now had a one piece rear main seal. The TPI 305 was the lucky recipient of the LG4 camshaft, and the result was a drop of 25 horses and almost a half second longer run to 60mph. Chevrolet did allow 50 IROCs out the door with the 220HP L98 350 TPI, but word has it, it wasn’t for production release. Beware when somebody sells an 86 IROC-Z with a stock 350 TPI engine. CHECK THE VIN for accuracy.
Chevy also let an undisclosed number of these cars out with the T5 (5-speed transmission) as part of the 1LE racing option that also included air conditioning delete, radio delete, as well as the deletion of all power accessories. The 1LE option was not available with T-tops, but did come with specially calibrated springs, shocks and sway bars.
Visually, not too much changed on the 86 IROC. The government mandated 3rd brake light found its way to the top of the rear hatch near the roof line. Curiously, rear window louvers became a factory option this year. Some of the 86 IROCS came with the new 140mph speedometer. 86 was also the first year for the base coat/clear coat paint system as standard equipment.
*A ‘unique’ feature of the 1986 IROC-Z, is that the third brake light was located on top of the hatch window, close to the roof. Later year, base model Camaros had the brake light in the same location as most did not have a rear spoiler.
*Colors available were White, Black, Bright Red, Yellow Gold, Bright Blue and Dark Red Metallic
*Most 1986 IROC-Zs have the 85MPH speedometer, regardless of engine option. Later on in production, the 145MPH speedometer was introduced on TPI equipped IROC-Zs, regardless of transmission.
*Automatic transmission equipped IROC-Zs had the round gear selector handle for 1986. All LB9 optioned IROC-Zs required automatic transmission
*The 5000 RPM redline tachometer was used on all production IROC-Zs for the 1986 model year, regardless of transmission.

1987 Model Year

Total Production 38,889
IROC-Z Option Code B4Z
Base Engine LG4 "Quadrajet" Carbureted 305 CID (5.0L) V-8
Optional Engine(s) LB9 Tuned Port Injection (TPI) 305 CID (5.0L) V-8 L98 Tuned Port Injection (TPI) 350 CID (5.7L) V-8
1987 brought about only minor changes to the IROC. The motors now had the new center bolt style heads and the intake manifolds had a revised bolt hole angle to accommodate the different heads. The motors also made the switch to hydraulic roller camshafts. This gave a 3.5% increase in gas mileage, and an extra 5 horsepower. The TPI 350 was now widely available, but only with the 700R4 automatic. Recipents of this engine wore the badge and the 305 TPI recipients wore the conventional badge.
Visually, the 87 is identical to the 86 model, except that the third brake light moved from up on the rear hatch, to down in the rear spoiler.
*On the 1987 IROC-Z, the third brake light was on the spoiler of the rear hatch lid. Base Camaro models still used the upper hatch location (towards to roof) for the location as most did not have a rear spoiler.
*Colors available were White, Black, Bright Red, Yellow Gold, Bright Blue and Dark Red Metallic
*The 145MPH speedometer was used on the 305 CID (5.0L) Tuned Port Injection engine (LB9) and the newly available 350 CID (5.7L) Tuned Port Injection engine (L98) equipped IROC-Z, regardless of transmission and includes convertibles with the LB9 option
*1987 was the first year you could get the T5 5-speed manual transmission behind the LB9, 305 TPI engine.
*Automatic transmission equipped IROC-Zs had the square-shaped gear selector handle for 1987.
*The 5500 RPM redline tachometer was used on all 305 CID (5.0L) Tuned Port Injection engine (LB9) equipped IROC-Zs with manual tranmissions, as well as all 350 CID (5.7L) Tuned Port Injection engine (L98) equipped IROC-Zs.

1988 Model Year

Total Production 27,811
IROC-Z Option Code Z28
Base Engine LO3 305 CID (5.0L) Throttle Body Injection (TBI) V-8
Optional Engine(s) LB9 Tuned Port Injection (TPI) 305 CID (5.0L) V-8 L98 Tuned Port Injection (TPI) 350 CID (5.7L) V-8
1988 brought about some welcome changes in the horsepower department, as well as a somewhat revised exterior scheme. The Z28 was discontinued, and the IROC was now its own model utilizing the Z28 RPO code (instead of the B4Z code). For the first time in the history of the camaro, no carburated camaros were available. All motors offered fuel injection of some sort. The base IROC motor had the TBI injection that was very similar to what was found on the trucks. A new camshaft finally found its way into the 305 TPI and boosted horsepower to 195 HP in the automatic version, and a stout 220 HP when backed with the T5, 5-speed manual transmission. The 350 TPI also got a small horsepower boost to 230 HP. All of the V8s, starting in 88, had "guided rocker arms" that featured a stamped-in lip on each side of the pad that contacts the valve stem.
The exterior of the IROCs received a mild update for 1988. The most noticable difference is that the wheels have been slightly changed. Instead of one line through the center of each spoke, there were now two lines (on the, now, optionally equipped 16" aluminum wheel), and the center area was a little different. Here’s an interesting tidbit: for the first time, the 16" wheel was an option on the IROC. The car came standard with a 15" version. Along with that, the IROC-Z decal moved to the rear of the door instead of the front. The stripe along the ground effects line now had the black line on top of the other. The silver Z-28 badges on the exterior have been replaced with orange IROC-Z logos.
*On the 1988 IROC-Z, the third brake light was on the spoiler of the rear hatch lid. Base model Camaros were the Sport Coupe model, consisting of either a pedistal mount spoiler (exclusive to 1988 we believe), or the three piece spoiler; either one consisting of the brake light in the spoiler itself as well. The base model Camaros received silver or grey ground effects and can be considered the "preliminary" RS as in 1989, the RS was the base Camaro and wore body colored ground effects versus silver or grey.
*Colors available were White, Black, Bright Red, Gunmetal Gray, Medium Orange (3,010 made) and Dark Red Metallic. 1988 was the only model year you could get an IROC-Z in Gunmetal Gray and Medium Orange.
*The 115MPH speedometer was the equipment now used on base equipped IROC-Zs for 1988. This would be the 305 CID (5.0L) Throttle Body Injection (TBI) LO3 equipped IROC-Z, regardless of transmission. The 305 CID (5.0L) Tuned Port Injection (TPI) LB9 equipped IROC-Z with the automatic transmission also recieved the 115MPH speedometer
*The 145MPH speedometer was used on the 305 CID (5.0L) Tuned Port Injection engine (LB9) with the 5-speed transmission and the 350 CID (5.7L) Tuned Port Injection engine (L98) equipped IROC-Z and includes convertibles with the LB9 option.
*The 5000 RPM redline tachometer was used on all 305 CID (5.0L) TBI engine (LO3) equipped IROC-Zs, regardless of transmission. The 5000 RPM tachometer was also used on 305 CID (5.0L) Tuned Port Injection engine (LB9) equipped IROC-Zs with automatic transimissions
1989 Model Year -
*The 5500 RPM redline tachometer was used on all 305 CID (5.0L) Tuned Port Injection engine (LB9) equipped IROC-Zs with manual tranmissions, as well as all 350 CID (5.7L) Tuned Port Injection engine (L98) equipped IROC-Zs.
*15" aluminum wheels were now the standard on all IROC-Zs starting in 1988. This particular style was only used for the 1988 model year only, replaced in 1989 with a style, similar to the newly designed 16" aluminum upgrade wheel.


1989 Model Year
Total Production 24,007
IROC-Z Option Code Z28
Base Engine LO3 305 CID (5.0L) Throttle Body Injection (TBI) V-8
Optional Engine(s) LB9 Tuned Port Injection (TPI) 305 CID (5.0L) V-8 L98 Tuned Port Injection (TPI) 350 CID (5.7L) V-8
1989 brought about some nice horsepower increases. The TPI 305 5-speed jumped to 230 HP if the dual catalytic converters were ordered (part of G92 package), and with the dual cats, the L98 350 TPI jumped to 240 HP, with a staggering 345 ft/lbs of torque! The TPI systems changed slightly. For the first time, the 9th cold start injector was no longer used. Visually, nothing changed from the 1988 model, except for one key item – starting in 1989, the rear seat belts were shoulder harness, whereas the 1988 and prior year Camaros used the rear lap belt.
*On the 1989 IROC-Z, the third brake light was on the spoiler of the rear hatch lid. Base model Camaros were now the RS model, basically the same car as the 1988 Sport Coupe, just bore the RS name, consisting of the three piece spoiler, in which the brake light would be located in the spoiler itself as well.
*Colors available were White, Black, Bright Red, Bright Blue and Dark Red Metallic
*The 145MPH speedometer was used on the 305 CID (5.0L) Tuned Port Injection engine (LB9) and the 350 CID (5.7L) Tuned Port Injection engine (L98) equipped IROC-Z, except for the convertible model, which used the 115MPH, regardless of engine (LB9 or L98)
*15" aluminum wheels were the standard on all IROC-Zs in 1989. The newly designed 15" wheel looks very similar to the 16" aluminum upgrade wheel option, just slightly smaller. To tell the difference, look at the tire size on the tire itself. For example, in 245/50/ZR16, the R16 notes that it is a 16" wheel and an R15 would signify a 15" wheel.


1990 Model Year

Total Production 5,517
IROC-Z Option Code Z28
Base Engine LB9 305 CID (5.0L) Tuned Port Injection (TPI) V-8
Optional Engine(s) L98 Tuned Port Injection (TPI) 350 CID (5.7L) V-8
The IROC-Z Camaro ends in a bang. This is the first year the 1LE high performance option became widely known. The 1LE featured 4 wheel disk brakes, a 3.42 posi rear end, an aluminum drive shaft, large 12" front rotors, aluminum calipers, engine oil cooler, larger anti-roll bars and gas tank baffles. There were also numerous spring rates available. The package could only be ordered without air conditioning or fog lamps. 1990 also marked the year the the TPI systems changed from the Mass airflow system to the speed density system. The speed density system allowed an extra 5 horsepower for the 350, upping the ante to 245 HP. The LO3 305 TBI dropped as the base model engine. The only engines you could get in your 1990 IROC was either the 305 TPI (w/ or without the G92 package) or the 350 TPI. Also, for the 1990 model year, the removable roof panels (T-Tops) were not offered in the 1990 IROC-Z equipped with the 350 TPI engine option.
*Visually, the exterior of the 1990 IROCs did not change, but looking through the windows will show that they now had a driver side air bag as well as revised instrument cluster. 1990 marked the last production model year for the IROC-Z, ending production as GM’s licensing for IROC ended December 31st, 1989. The limited number of 1990 IROC-Z’s is accounted for the number of cars produced, under the IROC license, until December 31, 1989 for the 1990 model year.
*Only in 1990, was the dash "IROC-Z" logo yellow
*The 5000 RPM redline tachometer was used on the 305 CID (5.0L) TPI engine (LB9) equipped IROC-Zs, without the G92 performance package
*The 5000 RPM redline tachometer was used on the 305 CID (5.0L) TPI engine (LB9) equipped IROC-Zs, without the G92 performance package
