o and io engines

wrote)
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.

The main reason the IO engine is more efficient is the compression ratio is
higher. The compression ratio is in the numerator of the efficiency formula,
so there is a direct relationship.
