13. Right after buying the Chevelle, we wanted to take it to the dragstrip--but it wouldn't stay running. After tuning it up it ran a not so good 16.72-second (altitude corrected) e.t. The time wasn't great, but neither was the condition of the engine (stock with 140K miles). After bolting on the Edelbrock intake manifold and PAW open-element air cleaner the car reduced its e.t. to 16.62 seconds. Other interesting performance stats included a not so impressive 60-0mph stopping distance of 188 feet and a speedo error of 45 mph! Is this the shape of things to come?
