Loaded G35S or G37?

Per my response in the other thread with a similar story line, the VQ37VHR is quite a bit different from the previous generation VQ35HR:
-328 hp vs. 306 (Sedan)
-First production engine from Nissan to use VVEL (Variable Valve Event and Lift) - Google this and watch the Youtube on how it works, very innovative
-Increased compression ratio of 11.0:1(vs. 10.6:1)
-Redline of 7600 rpm vs. 6800 rpm.
In addition, the VQ37VHR engine has been praised by the auto rags as a nice improvement over the VQ35HR in the way of refinement/smoother operation, especially at high rpm where the VQ35HR engine was criticized for NVH and sounding overworked.
I like the more technical summary found here: What changed from the VQ35HR to the VQ37VHR engines? > 370z.com > 370z.com - Magazine
"Nissan improved upon the VQ35HR engine in order to produce more power, cleaner emissions, and greater fuel efficiency. Approximately 35% of the VQ37VHR engine components are newly developed technology, from the revised cylinder head and increased height of the cylinder blocks to the VVEL operation as well as a wider phase CVTC on the intake side. The VQ37VHR also has higher flow exhaust ports, equal length exhaust manifold, longer connecting rods, and greater compression ratio (11:0 versus 10.6:1 in the VQ35HR). Nissan also enlarged the diameter of the crank journal and crankpin, enhanced the durability of the upper and lower oil pans, chain and rocker covers, and valve springs, and revised the oil pump rotor. It is equipped with twin knock sensor, a sound insulating engine cover, symmetric twin intake system, and high flow intake manifold and resin collector. The VQ37VHR offers about 330 horsepower and 270 lb-ft of torque, an improvement over the VQ35HR's 306 horsepower and 268 lb-ft of torque."
Also, take a look at the bottom end of this beast: Nissan 370Z Review; Engine (VQ37VHR) > 370z.com > 370z.com - Magazine
Essentially, it uses a bed plate style main bearing cap and can be built to easily sustain over 1000 hp without problems.
If the motor can be criticized for anything, its the fact that it is essentially 'mod-proof' because they are already squeezing everything they can out of it.

socketz67,
All that you said is true, but for an apples to apples comparison, the G37 6MT is still only marginally quicker than the G35 6MT. Maybe it's the weight difference as someone pointed out. The AT's are a different deal - ratios in the 7AT are more aggressive off the line.
