A decade before becoming the punch line of an ethnic joke, the 1985 Chevy Camaro IROC-Z became the lust object of thousands of teenaged boys, thanks to its 215-horsepower 5.7-liter (350-cid) V8 engine. Inspired by the International Race of Champions, the ’85 IROC-Z got unique front styling, deeper side skirts, and special 16-inch alloy wheels wearing wide Goodyear Eagle GT tires. Good thing Chevy introduced the IROC-Z: Ford was getting 210 horsepower out of the Mustang GT’s 5.0-liter V8 by 1985.
