Gross hp
SAE net 70's
SAE "Certified" Power started with the LS7 in 2006 which is rated at 505hp/470 lb/ft SAE Certified using the J2723 which is a voluntary 3rd party rating in addition to the J1349 rating of Aug 2004.

The 375hp and 405 hp LT5's are rated using SAE net hp, certainly not gross rating methods.

The 92-97 LT1 5.7 had a net raing of 300hp, which was about 377-78 gross hp which made it the highest output SBC in history eclipsing the 375hp fuelie 327 and 370hp LT-1 350.
