When it was all said and done, the mildly altered L72 427 cranked out455 hp at 5,900 rpm, substantially above its 425hp rating, even at thelower compression ratio.

Torque was stout throughout the curve, reaching a peakof 460 lb-ft, and showing muscular twist throughout the rpm range. View Related Article
