I just don't want the motor to be working as hard. Less boost. My tuner has already described the above, less boost at peak torque etc. See how it works. Regardless, many people have had issues around that power level with 4 bolt heads.

He's still day dreaming. Engine Dyno and in a car are two way different applications. Twin 6766 Precisions or 366 Borgs on a 5.3 with head studs and gaskets, cam, valve springs and pushrods is the way to go. No reason to give up power/torque with the shorter stroke.
