In case you missed it in your search on propane to get the best performance
out of a propane burning engine it needs to have somewhere around a :1
compression ratio as the octane rating of propane is pretty high. The only
problem with compression that high is that you can't dual fuel it and switch
back to gasoline if the propane runs out. OTOH the engine would have to be
built stronger to handle the higher compression and may last longer as a
result.
