Seems that doing this swap would actually make sense from a weight advantage. -97lbs

No doubt the S62 is bad ass as I've seen this Turner Motor Sport S62 engined M6 win its class at Homestead in 2010. That being said the the S65 raised the bar engine tech wise- or BMW ///M would have just stuck with the S62 no Especially seeing as though the E60/E63 saw the introduction of the S85 V10. What I'm saying here, is why go back to the drawing board- and create an all new engine if the 4.9 L S62 is lighter than the 4.0L S65 with comparable horsepower and more torque?
