I took a look at Van's catalog and they still list this GA composite prop for just the O-320 engine. However, Sensenich's site now shows that it is approved for the O-360 and O-390. Looks like the price is the same. Might want to talk to Van's and get them to update their web page.
I can't imagine the prop being much different on the O-360 than it is on my O-320. It is a great performer and easy to adjust.
