Horsepower god Kenny Duttweiler made many dyno pulls to determine the best horsepower and We took Cheap Street Chevelle to the dragstrip to determine its performance capabilities. It delivered consistent 13.50s at 100 mph running on pump gasoline and through the mufflers. For those of you who like stats for comparison, our '70 Chevelle weighs about 3700 pounds, runs a three-speed TH350 transmission, uses DTS 3.73:1 gears and rolls on P235/60R15 tires. If your car is similar to ours in size and weight and runs similar parts, you can expect similar dragstrip results. In addition, our rig is tame on the street and is fun to drive.
