The idea for using the VD version was to keep things as simple and direct swappable as possible. The DE has been proven to workin the 350 and drift 370z but you have to gut everything to make it happy.
Now, short stroking the motor while limiting the volume and travel wouldn't it also leave the motor more liable for a bent of torqued rod? My thoughts were to limit the amount of mass being propelled... Most of the time when a motor drops a rod it's usually from the sudden deacceleration of the piston head... Make that smaller and lighter and your rods and pins are less likely to fatigue and break. However, increasing rpm will create more friction and heat which could lead to burnt piston rings and oil consumption...
Also by deboring the motor you can run a flat plane crank without balancing shafts... You are effectively under the 2.5L per bank magic number where you are not getting too much vibration or harmonics from the opposing block.
