The Chevrolet Monte Carlo is an oft-forgotten model from the tail end of the muscle car era. It hit the market in the 1970 model year, bearing a 454-cubic-inch engine that cranked out either 360 or 450 horsepower, depending on whether it had the LS-5 or LS-6 engine, respectively. For the Monte Carlo, however, it was too little too late, as emission regulations strangled it down to a paltry 145-horserpower, 350-cubic-inch engine by 1973. The 2002 Monte Carlo’s standard 3.4-liter engine, which produces 180 horsepower, requires a spark plug change every 100,000 miles.
