I've done some searching, but I haven't found the information I need.
Looking past the inherent difficulty of making such switches, I'd like to know what differences exist between the LT2 and the LT3. Preferably we could discuss this in three stages. First, any long block and internals that may be different, Second stage, any exterior pieces that are different, i.e. The differences in throttle bodies/injectors, intake manifolds, exhaust manifolds and the like... and obviously there is a difference regarding a Turbo being on the engine, but lets discuss that too. These engines are getting difficult to find, lets talk about what needs to be done to add a turbo to a N/A engine. And lastly the peripherals; computers, transmission bolt patterns and the like. Anyone want to contribute, as I have no idea where to start, and these engines are getting harder to find.
