Looking at putting a new engine on my Lancair. Cowl is tight, very tight. It has a narrow deck O-320. Is the wide deck O-320 physically wider than the narrow deck motor?
So is POA?google is your friend....
Found that link already, read it, still don't know the answer to the question if a wide deck o-320 requires more horizontal space than a narrow deck inside the cowling.Check out this link - https://generalaviationnews.com/2009/10/07/ask-paul-wide-deck-vs-narrow-deck-engines/

FYI: this is dated info, but if I recall, the horizontal dimensions between a WD and ND are the same. But due to the cylinder differences the baffling will need to be altered and there can be other external differences with the mounts, etc. depending on specific model number comparisons. A call to Lycoming support with the P/Ns and S/Ns of the engines you wish to swap should answer your question specific to your aircraft.Is the wide deck O-320 physically wider than the narrow deck motor?
Thanks for the replies. My local mechanic thought they were the same width as well. I have read the narrow decks may be 10-15 lbs lighter though, unconfirmed. My plane tends to be nose heavy so less weight on the nose would be welcomed.
Need to find a motor now.
Done done it already.Replace prop with newer lighter composite prop.
Done done it already.
Battery was already in the empennage. I added a second battery in the empennage to help. The larger mkII tail on later models helped this some I hear.I don’t know Lancairs, but if battery is in the engine compartment, maybe you could move it into the tail?
