Ken... no one does that... just kiddin
If you have enough fuel pump to pump 30% more fuel
then the only factor would be the carb. I had mine
re done by Quick Fuels, this is a 1050 dom and they
were real close for everything but I did jet up 3
or 4 jets in it, idles great. There is www.e85forum.com
they have alot of good info. I've been running it most of
this past season and love the price difference from
112 octane to the E-85. I have some minor tuning
to complete this coming season with timing, I'm
thinking about 5* more
