That looks pretty good. I’ve been curious if the unibrow was going to be a performance problem or not.

Interesting to see how cool the cylinders run on that engine.

Kinda like my air-cooled Corvair conversion. When I started flying mine I was very surprised and enquired with the folks that know these things as to why it ran so cool, even in the summer. I was asked what problem I was trying to solve … :wink:
