The combo you have- 354ci, 3.47" stroke/5.4" rod - will always favour low end torque , which is great for street use etc. With the 8.2" deck height you cannot really improve on this without going to an expensive custom piston with a pin height around 0.900" and the chevy 400 rod @ 5.56".

One point on the print out, did they give you a reason for the 'ripple' in both the tq/hp lines in the 5250rpm region , ignition- fuel supply-revlimiter-valve springs-wheelspin ?
