The only differences mechanically between the camaro and vette ls3s are oil pan, one valve cover and the exhaust manifolds. The manifolds and a slightly different tune are what accounts for the power differences.

The truck 6.2's can be had for half the price and are essentially the same motor, especially if you are going to cam it anyway. The only thing that you really can't change cheaply is the slightly lower compression and the lack of lightweight valves. But even with afm/vvt delete and a car intake setup you will be well cheaper than the actual ls3.

The later 6.0s are also a great choice, same rectangle port heads, just even lower compression, but are even cheaper than the truck 6.2's.
