Without wishing to appear like a
, I would like to say that the "A" model definitely has the Lycoming 360 (180hp). It was only produced for one year and was Cessna's stepping stone between the standard 150 hp "177" and the "177B".
I nearly bought one and did much research on the subject.
Decided against it as the wife said it was ugly. She has no taste though (except in men of course.....
