The best conversion that I've seen is the Continental 550s, with over 300 horsepower on each end, the Skymaster jumps off the ground like crazy.
I've flown a few PT6s converted into single engine and they fly quite well and also.
IO-550-N engines, Hartzell Model PHC-G3YF-2UF/F7663D-2R propeller front, Hartzell Model PHC-I3YF-2AL/FLC7663DF-2 propeller rear, front and back AirScan engine installations and 5120 pounds Maximum Gross Weight
