I know that the 3.9L v8 in the LS is supposed to be based off the 4.0 aj28 engine, I've read on some forums that the only jaguar based part on the engine is the block minus the nikasil liners replaced for iron ones. I know the s type had continuously variable valve timing, but everything else, at least design wise, seems to be the same. There's various differences here and there but other than the cvt and 46cc of displacement is there really a difference between them? The engine bays look identical, and so many parts are interchangeable that are unrelated to the block, what exactly is different about them? It seems like the cvt is the only real contributing factor in the 30 hp difference.
