Under the hood is the factory-stock 350ci V-8 engine. This engine only has about 66,000 miles on it and Hairapetian reports that it runs great. As it was in 1972, it’s topped with a four-barrel Rochester Quadrajet carburetor. The only performance mod to the engine is to flip the top of the factory air cleaner housing upside-down (old timers will remember this trick, which returned dubious performance but sounded good under load). The engine is cooled by the factory three-row radiator, and exhaust gases are routed through the stock diameter exhaust tubing and through a three-chamber Flowmaster muffler.
