In general the limit for connecting rods and power is dictated by torque. I have not seen a set of rods from this car not do I know how they are made so I cannot comment on this. I do know that being 8 cylinders, the torque is spread across a little better than the 6 cylinder GTR's. For example a 650 ft-lbs torque V6 is about 108 ft-lbs per cylinder, on the V8 that would be only 81 ft-lbs.
Also to clear things up, Dynamometers don't read torque at the wheels, they calculate engine torque through HP and engine RPM. 600 ft-lbs of torque at the wheels would make for a very slow car. That 600 ft-lbs get multiplied through the gearing, differential, etc to get to the wheels.
