Finally, at 22 psi, with the spark blowing out, Jamey saw the dyno hit 954 hp at 6,800 rpm and 742 lb-ft of torque at 6,400 rpm. Unfortunately, the dyno tech had to cut the session short, leaving no extra time to pull the Autolite 103 plugs and close the gap from 0.030 to 0.020 inch and achieve the 1,000 hp goal. Jamey blames the spark issue and pig-rich air/fuel ratio for barely missing his 1,000hp target. He views hitting this figure as merely a formality as he tinkers with the street tune.
