like a motorcycle engine - strip it down and just build the parts and
accessories required to make it turn a prop. And along the way one can
also machine it's component parts down to lighten it...run it on the

Anything that flies a person has to be certified by the FAA anyway.
Especially homebuilts due to some fatal crashes early on.

The FAA licensing process for homebuilts is much lighter weight than for
'regular' aircraft. People can and do convert automotive engines for
homebuilts, and fly them. There are many building processes that aren't
certified for general aviation, but which are acceptable to the FAA
inspectors for homebuilts.

Check the EAA website (eaa.org?) -- they'll have something.
