It would probably work fine. It has lower compression ratio pistons - maybe 8.0:1 I think.
Make sure of the induction system. All kinds of manifolds were used on those things - natural gas, propane , gas with a governor, etc. You may have to upgrade. Likewise the exhaust may need upgrading. Good luck.
