Put that Continental IO-360 on and you will see a still better climb and cruise and still retain the smooth 6 cylinder like you are used to with the O-300. All it takes is $$$

That's a matter of opinon, of course, but if I were to re-power it would not be with a shaky 4-cyl Lycoming. It'd be with a Continental IO-360 (which puts out from 195 to 210 hp and does so with smooth-running six-cylinders, and which is kinder to the cowling.

Guys thanks for the feedback on the 170 climb rate and the prop education. I have more realistic expectations and can ask better questions going forward.
The 170A I was looking at did not work out, so I'm back on the hunt!

And that's a good thing because the more you look the more you'll know when your close.
