Figured I might as well add this in here as a datapoint for those interested, having just ordered a new donk from ECI.
An OX-340S with:
- 7.2:1 Pistons
- Dynafocal 1 mount
- 14mm plug bosses & automotive plugs all round
- Dual P-Mags
- Low-pressure, engine-driven fuel pump
- 2 hours break-in on their test cell
- But without a carb
is going to cost me
$25,604, including crating but excluding shipping - which given I live in Australia is likely to cost more than the engine anyway.
A new carb would add ~$1,500 to the price, but I'm going to install the locally-made Rotec TBI in its place.
The -340S with the low compression pistons will allow regular running of Mogas with an increased detonation margin while still delivering ~160HP, and also fitting in the footprint of an O-320. Cheaper flying is always a good thing.
