The Power Flow is a great product- They work well on an E or F. They still provide benefit on the J models but not as much because of the better exhaust on the J.  

power flow can also be installed on the 390....

You have Western Skyways overhaul on your list of options.

There is nothing Western Skyways can do that Jewell can't. The difference will be 50% of the cost or less.

well, for starters.  Jewell doesn't have cores on the shelf, so no overhaul exchange option.  when i asked about the A3B6 conversion from the D the conversation started like this "Jesus Christ, I don't know what everyone infatuation with this is".  Mainly the conversation trended with the tone I was an idiot.  I've heard good things about Jewell, but i think ill stay the course in a different direction based off that conversation.

Had my overhaul with Jewell and had a great experience. Might have been a bad day for them. They were prompt and very informative with pictures of the progress also.

if you don't mind me asking, could you share either here or PM the total cost?

I believe it was around 21k. That also included R&R

I literally just completed what has been a over 2 year project replacing my single drive dual mag in my 78J.  The engine swap didnt take that long but the time it has taken to do the extras did, including EI engine monitors, SureFly electronic ignition, etc, and its been flying about 150 hrs during this whole project.  I can tell you a rebuilt Zero time engine from Lycoming is worth every penny, enough so that when I TBO this engine out I would very strongly consider doing it again and forgo the overhaul route.  The difference in cost between overhaul and reman is instantly made up in the increased value of the plane which now has a zero time engine in it.  Additionally, most of the components on my reman were new because Lycoming has not received many of the A3B6's back in cores.  So many benefits IMHO to going the reman route verses overhaul...the biggest and only downside is the upfront cost of the extra $7500ish.  I could go on about a reman vs overhaul but it just went really well in my experience, especially considering what my end goal was.  Fuel economy is also a great benefit with electronic ignition, another reason to deep 6 the A3B6D, along with simply starts, hot or cold...all the time!  I digress....

The only reason Lycoming gets to call a rebuilt engine Zero time is because they don’t know what else to call the pile of parts they pull off the shelf for reassembly.  
 

The only true Zero time engine is a new one.

That’s absolutely true. They do use a lot of new parts and you get new cylinders and it’s built up to new limits on the same line as new engines and run in in the same test cell. But, some parts, like crankcases for instances, could be two or three engines old and there’s no way to know.

the oldest roller case is 2005, so I dont think many cases are that old. I got two of them, both new cases.

I also have a core engine 2006 roller case in my shop.  A field overhauler can build that too.

Sent you a message on the core.  Thanks
