In a 95" build based on boring out an 88, with hotter cams, etc., you're looking at horsepower over low end torque, IMO.

My take on why they stroked instead of bored was so they could sell more >98" big bore kits without requiring the case to be cracked open for the stroke. That was always the big money prohibitor to people going above 98" with their 88". Now you get an engine that is already stroked, and you can slap on all sorts of bore upgrades in the form of kits from the moco. I see this as a pure sales stragety decision.
