This IS "Over" 500/500
POWER-TESTING THE FINAL PRODUCT
Livernois Motorsports is experienced at building all kinds of LS engines for street
and racing applications. The company likes the LS7 as a wet-sump engine
because it makes just as much power throughout the rpm band as the stock
dret-sump, installs anywhere a normal LS V-8 engine would go, and has incredible
street cred. The wet-sump LS7 is not for customers wanting a track-ready Pro
Touring car—in that case, the dry-sump version of the LS7 is ideal.
Note: Power numbers are all corrected using correctionf factor SAE J607 (29.92
Hg, 60 degrees F, dry air) and testing was performed with the GM Performance
Parts controller (GM PN 19166567) handling fuel and ignition.
