Ive been reading that to build an engine to take full advantage of e85 or LP that the compression should be bumped to 12-1 or so. So would it not make sense to use those two fuels instead of gasoline plus either?

Ive got a 72 351w going in a 64 f100. And dont want to run regular gas for many reasons. So would that be a better dual fuel setup? As far as the engine is conserned.
