Going with IO-390 for M20E. 2-blade prop or 3??

If a port/polish is that cheap, maybe I should have them do it on the 390 at instal    I'll ask if that is doable. 220HP with the Powerflow??

You may want to check that the Scimitar is compatible with the Power Flow

The IO-390 in a box with core exchange etc was about the same price as an IO-360, but the prop made it too much.

 

Where did you get these prices from? Can the core for a 390 be my old 360? I've had a scimitar prop from when they first came out so that's a non-issue for me, but my 360 has had friggin issues with oil leaking/burning/blow by since I've had the plane. I'm tired of dealing with it and pretty close to just biting the bullet and getting an engine from the factory.I was thinking about the 390, but the cost from their website is in the mid 50's. Any information would be appreciated.

ditto, I am in the same boat (I mean plane)

 

FWIW, the 390 does not help with access to the oil screen, nor with hot starts (both remain potentially painful)

It is not as bad as you think. Trust me. When you see $50k on the Lyc website, it doesn't really mean $50k. Get your mechanic or Lyc Service center to price it for you and you'll be pleasantly surprised. I am going through TriadAviation at KBUY.  It is not as bad as you think and not that different than getting your tired beater IO-360 overhauled. More expensive? Of course, but not so bad in my opinion. There are more and more 390s out there in the EXP world, so I think that going 390 will be ok in the long run.

 

I have no idea if a 390 case is just a 360 case bored 1/8" to accommodate slightly bigger jugs. That is what I imagine it is.

 

BTW, although Alamo Aerospace did the STC, Lycoming owns the STC (which you might have to remind the Lyc rep of.... they got confused today), so buying the prop through them is the way to go as well. Apparently, H&H (Triad's siamese twin Prop shop, run by a great Thai fellow named Yoo ) was told by Lyc rep today that we'd have to go through Alamo. The rep was mistaken.

You can buy a 390 from any Lycoming distributor - experimentals do it all all the time -  . To buy the STC'ed for Mooney 390, you have to go through a Lycoming Authorized Service Center who will do the install. At least, that's my understanding, or maybe things have changed.

 

Please keep me posted.
