Lot 2686-CHI: 1985 Chevrolet Camaro IROC-Z

For the 1985 Chevrolet Camaro IROC-Z, there were three engine options available:

Original Engine Options:

1. LG4 305 V8 (155 hp) - Base engine
2. L69 High Output 305 V8 (190 hp) - This is what’s in your listing, paired with a 5-speed manual transmission
3. LB9 Tuned Port Injection 305 V8 (215 hp) - Available only with automatic transmission

Notable Performance Upgrades for the IROC-Z Package:

• Upgraded suspension with specially valved Delco-Bilstein shocks
• Larger diameter sway bars for improved handling
• Lowered ride height for better aerodynamics and cornering
• Steering/frame brace known as the “wonder bar” for increased chassis rigidity
• Special 16-inch aluminum wheels with performance tires
• Unique aerodynamic body package with special decals

The L69 HO engine in your listing was actually quite special - it featured a 9.5:1 compression ratio, four-barrel carburetor, and was only available with the 5-speed manual transmission in the IROC-Z. It produced 190 hp and 240 lb-ft of torque, making it a significant upgrade over the base LG4 engine.

The IROC-Z package transformed the Camaro from a sporty coupe into a serious performance machine, with suspension upgrades that made it competitive on the track while still being streetable for daily driving.
