It would be possible in theory - that's 84 ft-lb/L and Ferrari has hit 89 ft-lb/L with the 4.5L V8 in the new 458 Italia. Granted that has a flat plane crank and revs somewhat higher also.
However, I agree in context it makes little sense. The S65B40 makes about 300 ft-lb, so expecting such a huge increase in torque from a 10% displacement bump is pretty off-the-wall. Plus, I doubt that the torque curve of the Ferrari V8 is as flat as that of the S65. As we know, it's not just about peak torque - total area under the curve is important.
