From the web, google LS1 LS2 differences......"The LS2 has a 4.00" bore as opposed to a 3.89" bore. The cam position sensor has been relocated to the timing cover, and the knock sensors are on the sides of the block as opposed to under the intake valley. It uses the same heads as the 2002-2004 Z06, however it does not have the same sodium filled valves. It uses a revised intake manifold with a 90mm tb instead of a 78mm tb, and the injectors and fuel rail is different too."

Also the HP difference is about 50.
