The Sky was offered as a BaseLine and Redline. Back in 2007, if it was also offered as a HotLine LS2-V8 n/a version, everyone here (including myself) would be saying that is the Sky to own. But any kind of aftermarket conversion has it's various concerns, primarily part availability, followed with serviceability. Some people might even include reliability.
With that said, it would be interesting to see a complete list of every off-the-shelf part required for a factory-like LS2 conversion (engine alone) and also what custom-made or modified off the shelf parts. Have separate lists for brakes, wheels & tires, suspension, and transmission recommendations.
