If anyone is interested. I can put you in to my build position at LyCon for a Lycoming IO-390.
My engine was planned to start with a Lycoming Build Kit of all new Lycoming parts for an experimental IO-390. The engine was planned around my need for mounting the engine, which I had estimated to be October. It was planned to be built by August, placed on the shelf, and wait until I was ready to mount before running in the test stand. What that means, is that it could be ready as early as August. The caveat to that being this is being built by one busy engine builder, and I think you would need to be somewhat flexible. I live a mile from LyCon and have a friendly relationship with the owner and his brother.
I had planned numerous features that LyCon offers to be built in to the engine. It is still at a state where it could be built to factory specs, or have LyCon do all of, or some of the features they offer in a custom build.
The way I was building it. . . it was estimated to be somewhere around 235-240hp
But HP costs money. . . you don't need that much. Obviously. I just wanted
Give me a shout. PM me and I can make contact via phone or email.
