Here is the specs with a reduction drive. Note the peak power is at 1870 shp at 6000 rpm with tq being 1270 at 6000 rpm.

Then...more importantly...peak Tq is 1800 ft/lbs at a mere 1200 rpm. Used with the right tranny...and rear gearing this thing could fly. Note the weight of the powerplant as well.
