You are absolutely right about the motor. It's the same motor (minus the SC) as the big body cars with the superchargers pumping out 470hp-510hp (depending on model.) Without the added stress of the supercharger you can expect the N/A variants to last.
Check out this snippit from Wiki: http://en.wikipedia.org/wiki/Mercede..._5.4.C2.A0L_V8
This car has the 722.6 transmission: http://en.wikipedia.org/wiki/5G-TRONIC
This transmission is designed to handle 796 lb-ft from the AMG-65 motors.
TL;DR <PROVEN> This car's engine/tranny combo is bulletproof.
