52er you've touched on a few good points. I don't think you will see a change in mix any time soon. The 15% Ethanol in gas is enough to cut the emissions. The 15% gas in Ethanol (E85) is enough that you so you don't have to prime the motor to start it. Ethanol not being good for old cars is correct, will cause the performance to suffer and the mpg to decrease by about 30%. You can get back part of the performance and mpg by raising the compression 4 points which will get you about 15%. My machine pointed out to me when I was looking for longer rods for my 292, The rods in the older motors were not designed for high compression.
