That sounds a bit like the story of the RV-6. I thought it was
originally intended for the O-320, and as more and more builders were
apparently successful with O-360 installations, Van designed the RV-7
with that (among other changes) in mind.

I built, own and still fly after 18 years the second customer built RV-6
and it has always been designed for an O-320 Or a O-360.
