You might look into the O-360 Lycoming for this airplane too.
The XP-360 is a lotta bang for the buck.


If it were me (and it almost was), I'd do the O-320. You don't have
enough tanks on the -9 to properly feed a -360, and you don't need the
extra weight. Plus, the -9 has enough wing that you don't need a ton of
power to drag it into the air.

Why do you say this, Jerry?
I think Ed is on extremely safe and sane ground.

Next thing you know, someone is going to defend morphing
the RV-4 series into Harmon Rockets and its hotrod clones.

Van as a most successful designer could offer a version.
Anyone ever stop to think of all the *PRACTICAL* reasons
why he does not?
