Great news - Got this from our clubs's NCM rep:

GM Is First To Certify Horsepower and Torque Under New SAE Test Procedure - Corvette Z06 now rated at 505 horsepower

General Motors has become the first manufacturer to certify its horsepower and torque rating using the new Society of Automotive Engineers (SAE) test procedure J2723.

The 7.0L LS7 engine for the 2006 Corvette Z06, the first engine certified under the new test procedure, was rated at 505 horsepower @ 6300 rpm and 470 lb-ft @ 4800 rpm, five horsepower more than original estimates. "The new voluntary SAE power and torque certification procedure ensures fair, accurate ratings for horsepower and torque as it uses third-party certification," said Jim Queen, GM Vice President, Global Engineering and the General Chair for the 2005 SAE World Congress. "SAE technical standards level the playing field and this certification procedure is just the latest example of the value SAE has offered over the past century." Tom Stephens, Group Vice President of GM Power-train stated, "We're very proud to be the first to certify engines with the new procedure and pleased with the LS7 certification results. Going forward, GM will certify its engines to the new procedure as we want customers to have accurate information when they make a purchase decision. GM encourages all manufacturers to do the same."
