My name is James Villanueva, and I live in Sweetwater, a small west Texas town situated approximately 39 miles west of Abilene. I created this web site to commemorate an authentic (B4Z) IROC-Z that I rescued in early March 2019. Here, I will document the repairs and improvements implemented to revitalize this iconic machine, sharing the journey of breathing new life into a classic.
This 1987 Chevrolet Camaro IROC-Z, assembled in March 1987 at the General Motors Van Nuys, California plant, boasts a comprehensive list of desirable features. Equipped with a Tuned Port Injection engine for enhanced performance, it also includes removable glass roof panels, a custom cloth interior, and the highly coveted G92 performance option, enhancing its overall appeal.
Camaro models equipped with the G92 Performance Option boast significant performance enhancements. These include front and rear disc brakes for superior stopping power, an engine oil cooler to maintain optimal engine temperature, and a durable Borg-Warner heavy-duty 7.75-inch four-pinion rear end. This robust rear end features a limited-slip differential and a 3.23 gear ratio, contributing to improved traction and acceleration.
Under the hood, the anemic LB9 5.0-liter (305-cu.in.) engine was ditched for its big brother, a period correct L98 5.7-liter (350-cu.in.) engine. The conversion was professionally completed and includes all necessary hardware and electronics, such as larger 24lb fuel injectors, an ESC module, a knock sensor, and an ECM equipped with an ABWN PROM.
The L98 5.7-liter engine is paired to a 700-R4 (4L60), 4-speed automatic transmission with overdrive and is advertised to deliver 225 horsepower and 330 lb.-ft. of torque to the rear wheels. While those numbers may not be impressive by today’s performance standards, the 3rd-generation Camaro retains a strong following among enthusiasts and is fast becoming the modern era's vehicle of choice among collectors.
This Camaro features dark medium gray custom cloth bucket seats complemented by matching carpets and a contrasting black dashboard, console, and upper door panels. A refresh has revitalized the interior with new carpets, floormats, and meticulously crafted period-correct seat upholstery by Lethal Interiors of Milton, Florida, expertly installed by Luis' Upholstery of Snyder, Texas. Staying true to its heritage, this Camaro comes well-equipped with a variety of accessories and options ensuring a sporty and engaging driving experience.
This Camaro offers a host of creature comforts such as air conditioning, electric rear window defogger, rear compartment cargo cover, and locking rear storage. Power features include a 6-way power driver's seat, power windows and door locks, a power hatch release, and power exterior mirrors. Further enhancing comfort and convenience are an auto-dimming rear-view mirror, an overhead console, comfort tilt steering, and cruise control.
Steering inputs are made via a black three-spoke leather wrapped steering wheel that frames a 145-mph speedometer, a tachometer with a 5000-rpm redline, and gauges for coolant temperature, voltage, oil pressure, and fuel level. The five-digit odometer currently shows 108,000 miles and I have every intention on seeing those numbers climb throughout the years.
This Camaro retains a factory UX1 Delco stereo, (Radio, AM-FM Stereo, Cassette, Clock, S/S, Equalizer) that has been fitted with an internal Bluetooth module so that I can connect any Bluetooth digital device to provide the tunes, when I prefer not to hear the rumble of the fuel injected 5.7-liter 350 engine. The air conditioning system has been upgraded to the modern R134a refrigerant and blows ice cold air.
Maintaining its original iconic stock appearance with only minimal upgrades, this Camaro IROC-Z offers a nostalgic driving experience. While not in pristine condition, it's lovingly garage-kept and enjoyed during the summer months as a fun weekend car. This timeless classic is intended to be cherished, driven on scenic routes in good weather, and proudly displayed at cruises and car shows alongside my son, creating lasting memories.
Rescuing this Camaro was a challenge I knowingly accepted, fully aware of the substantial investment of time, money, and effort required to restore it to roadworthiness and presentability. After a meticulous assessment of all its issues, "Operation Blue" officially commenced.
Chevrolet's third-generation Camaro Z28 took center stage with the introduction of the IROC series. This iteration of the classic pony car would ultimately become intrinsically linked with the IROC name, solidifying its place in automotive history.
