What that stuff does is try to reduce the chance of breaking. But, it does not completely eliminate the chance. Different uses of the car, pot luck on whether your engine has an .007" gap while someone else's has a .015", etc come into play. Not to mention, you cannot run E85 on a supercharged LT1 without some extra work and expense. To be able to run E85 on a supercharged LT1 costs somewhere around $2000 (LT4 parts and flex sensor) just for the parts and that's the low end of the pool. Cannot turn it up very high and still have the fuel system supply enough E85. While I think E85 is a good idea, for the multiple reasons that you mentioned, what that extra expense does to the value equation cannot be ignored.
