The then recently developed 150-horsepower, 301-cu.in. Pontiac V8 weighed significantly less than the Pontiac 400-cu.in. engine, and “is original” in this car, the seller notes. Approximately 2,000 miles have been added since it received a new, slightly more aggressive camshaft and was resealed in 2005. The original Rochester Quadrajet carburetor and catalytic converter have been retained.
