The IO-360 thus has a lower specific fuel consumption (the per-hour fuel
flow required per hp produced). Reason: I think the main one is that the
better fuel distribution on the FI engine allows operation with a leaner
mixture.


Curious - If approval from the FAA was NOT a factor:

How difficult, practical, expensive, etc, would it be to convert an O to an
IO?

What all would be involved? What would go, what would stay, etc?

Thanks.
