I have heard of people using av-gas in HIPO motors, never heard of it in a 235. I have seen some people try to use it in a stock 80's f@rd and not only did they trow a rod real quick but it also melted their fuel lines and destroyed the fuel pump, not sure what kid of av-gas they were running.
If you plan on trying this out make sure your lines are rated for the fuel you use and let us know how it goes a video of that would be interesting.
