The LS2 is the new factory engine for the model year 2005 Corvette and replaces the LS-6 factory production engine. The factory production LS-6 engine is no longer available but GMPP still has all of what you need available for an LS-6 if you still want one. GM gives the following write-up on the Corvette LS2 combination:
LS2 V-8 The 2005 Corvette features the new 6.0L V-8 LS2 engine based on GM’s Gen IV small-block family. The LS2 is the most powerful standard small-block engine ever offered in Corvette, and features: * All-new 319-T5 aluminum deep-skirt block casting with cast-in-place iron cylinder bore liners and cross-bolted main caps * Cylinder head design derived from the C5 Z06 * Camshaft lift increased to take advantage of increased head flow * Revised exhaust manifolds are 34 percent lighter * Compression raised to 10.9:1 * More powerful engine controller incorporates all electronic throttle control functions * 400 hp (298 kw) * 400 lb.-ft. of torque (542 Nm). The LS2 helps the Corvette achieve outstanding performance, including a top speed of 186 mph (300 km/h), making it the fastest production Corvette in history. It reaches zero to 100 km/h (62 mph) in 4.2 seconds, and in 4.1 seconds with the optional Z51 Performance Package, and covers the quarter-mile in 12.6 seconds at 114 mph (183 km/h). In ’05, the new LS2 also becomes the standard engine for the Chevrolet SSR (390 hp / 291 kw and 405 lb.-ft. / 549 Nm of torque) and Pontiac GTO.
Overall, the LS2’s output performance specs look to be almost identical to the LS-6’s with just a slight decrease of 5 HP at 6,000 rpm and shifting lower of the peak torque point from 4,800 rpm to 4,400 rpm. Again, you have to keep in mind that these specs are based on the vehicle they came in with everything that goes with that and at the rear wheels or (SAE net). The specs are not a direct comparison of engine to engine like all the crate engines that rate the HP and Torque at the flywheel with strict dyno testing guidelines.
P/N LS9750 does not include the computer, beauty covers, alternator, starter, belts, brackets, or pulleys apart from the crankshaft pulley. It comes only with what you see in the picture above left. The above right picture shows what a more completed engine looks like.

Brackets, wiring harnesses, and computers for the LS1, LS2, LS6 and LQ4 can be obtained from Street & Performance.

Note: These are factory engines and the specs given here are for the engines when installed in the factory vehicle they were used in. HP and Torque ratings are at the rear wheels for those vehicles. Your performance results for your may differ greatly from these specs if you have a poor exhaust system and larger losses through your vehicle's drive train, weight, rear and transmission gear ratios, tire size, brake drag, and a few other variables that will effect the final rear wheel ratings for your vehicle.
