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.
www.faa.gov the eaa is a pilot organisation, not a controling
authotiry :-)

your correct, the EAA will have a lot of information on homebuilt and
experimental A/C, they will also want you to get regular inspections
during the construction, even on experimental I think, and at various
benchmarks during the build.
personally I wouldn't fly with any home made engine, and by home made
I'm talking about things like casting your own cylinders etc, why
re-invent the wheel when there is a plethora of R&D'd engines that can
more easily and cheaply be converted.
My feeling was that while the FAA will give you enough rules to make a
swamp, the EAA will give you a map of the swamp so you can get through it!
