Here is the 2005 GTO 6.0L LS2 engine. The LS2 engine has 400hp and 400ft-lbs of torque. This thing puts out 50 more horsepower and 34 more foot-pounds of torque than the 2004 GTO LS1 engine. Here's a list of some of the changes on the LS2 engine: larger intake, stronger floating wrist pins on flat-top pistons, less-restrictive exhaust, improved heat shields, more efficient combustion chamber design, higher compression ratio, new E40 ECM with integral electronic throttle, higher lift camshaft, lighter water pump, lighter smaller oil pan, lower tension piston rings, and a crankcase vent redesign.
