Were those numbers the uncorrected HP and torque, or were they SAE corrected numbers? If they were uncorrected numbers what Temperature, Humidity, and Altitude when tested? What were the RPM at peak HP and peak Torque?
Very important questions here for consideration of your combo before you just start changing things out.
Where I am at, physical altitude is 5500 ft. Density altitude can be 10,000 or more on any given day. I have seen many "500" horse big blocks strap on the chassis dyno and crank out a whopping 180-200 RWHP. There is nothing inherently wrong with any of their combos, but high altitude combined with warm, thin air will kill power in no time. The same combo at sea level with dry air is a whole 'nuther story.
