You'll benefit across the board if you optimize your cam profile to take advantage of the ratio, but it's going to help your torque more than anything.

Higher pin location is good, I'll assume you haven't offset the pins.
Shorter skirt, lighter piston....
Better cylinder filling and evacuation, IF the cam is profiled for it.....
Should be able to run less ignition lead, adding to cutting down on the load during the work cycle.

It's all good......the rod weight at the beam will make the least difference.
