You failed to say what kind of engine you and the Pantera have and when the cars were built. You will almost certainly have issues with almost all fuel lines and plastic parts that were not specifically built for alcohol fuels. You should also be aware that the bladders and baffles in the fuel tank will probably not like it either.

In other words you have more homework to do. Else let us know how it works out.
