The builder David Taylor may be one of the view out there with enough resources to be able to do that, assuming there is enough interest.

I emailed David Taylor and gave him a link to this thread. It would be nice to hear from him about his project.

Jim,
Thanks for sending Dave an email on this - it would be great to find out how it is working. I doubt we will ever see this as an STC, and I think this is a little easier to do in Canada under the Experimental Catagory.

All the research I have done (which is very little) on this engine in the Republic Seabee, has converted the way I look at engine options. I especially like the idea of ease of parts (any GM dealership or O'Reillys) and the ease of having accessories like air conditioning.
