If I were looking for a replacement engine I think I would turn to S&S as they would have experience of the M3W and it's application and would like to think they would be up for the challenge of getting one of their engines to fit
I think you will find them running to the hills rather than the other way.
Why would that be, they would be potentially selling engines
Look at it this way. They already had the Morgan market and sold a few thousand of the Wedge motors between Morgan and other bike custom companies. BUT, they decided to drop that market completely. I highly doubt they would just at the outside chance at converting maybe 50 or so motors over to some of their other models. They did NOTHING other than sell an engine package, not ever sure if the EFI was theirs or someone else's. But all new mounts, exhaust, you name it, would have to be developed.
When it gets right down to it, I'm sure that parts will be found to keep your current motors up and running. Pistons and rings are available from many manufacturers along with valves and cams too. There's really nothing wrong with the current Wedge motor setup and they are of a larger displacement than other alternatives at this point.
