Uh, and your point is???/

The factory rods and pistons can easily withstand 330-350 ft-lbs of torque. I've already done that. IF the rpm range is stock, calculate what 330 ft-lbs of torque will be at 6500 rpm?

EXACTLY!!

As far as balancing, it is perfectly ok and sometimes worth the money to get a factory setup fully balanced. Not everything comes right(correct) from the factory....as is evidenced by some motors spinng smoother than others from the day the roll off the assembly line. I wouldn't do it unless I was updating the motor and felt that it was a bit too harsh when revving.

So you are correct. Why waste the money? I wouldn't.
