Hi,

Our C172 O-320 is well over TBO and needs new cylinders. We are
thinking we might just bite the bullet and get a new engine at this
stage.

The Penn Yan Aero SuperHawk STC looks like a good option since it
would give us 180 HP - a nice extra safety margin for our short strip.

Has anyone here had any good or bad experience with this engine?

TIA for any info via post or email,

Z
