IO-360 Helicopter Engine

[Cameron]

I found an Acrosport II that I am somewhat interested in, but I found out something aboutit that peaked my curiosity. It has an HIO-360 in it, which came out of a helicopter. The owner said that it was a beefier engine and that its redline was actually 100 rpm higher than a regular IO-360. He also said that alot of aerobatic airplane builders liked these engines for those reasons. I have no reason to doubt him, but I was just curious, and wanting to know more about this. Can anyone comment?


Thanks,
Cameron
