Hi guys,
A friend would like to know what pitch Sterba prop is the best for max cruise speed in his -4 with a 160 HP Lyc. He has a bead on one but doesn't know for sure about the pitch.

Thanks,

78"

Ed recommends a 68 X 78 for the 160HP RV4. I hope he's getting a good deal on the prop. A new one is only about $600.
