I didn't want to add more to the 8.1 sticky, but I have found a couple 8.1 propane engines that are cheaper than the gassers. Other than fuel rails and injectors what needs to be swapped on these to run gas?
 
??? Seen them new at the propane trade show . .not sure if compression ratio??

Propane fuel is 110 - 120 octane
 
never had a propane setup 8.1 .

but what i have heard is injectors / fuel rail and pcm . then its back to gas motor .

Just figured that if you had gotten that engine with no heads running (on gas), then you've already answered the question.
