Detroit - 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 is the first to be certified under the new test procedure at 505 horsepower @ 6300 rpm and 470 lb-ft @ 4800 rpm.

"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."

Originally, the LS7 was rated at 500hp. The the SAE changed the rating procedure, so the LS7 picked up those 5 extra hp without changing anything on the engine!!
Much like the L88 was rated at 430hp...that was a true figure...it was only true at 2500/3000rpm, tho!!!
