Wow I love all this speculation. Now here are questions I pose to myself and hopefully some people can answer reasonably.
1. How much weight would be saved going from the 6.2L to the new 5.5L (aluminum block right?) from just switching out engines?
2. Why not give the V6 the 3.0L LF3 engine! GM's got the engine, hopefully, they are just finishing up testing it.
