E85
not a pro on this ,but here is the kinds of things I have heard
about 30 % more fuel consumpion
carbs need to be modified,both gaskets and sizing
can handle high compression motor no problem
the same motor on racing fuel will make more power on E85 if all is done right, some say up to 25 %. ????
may need to run larger fuel lines and pumps need to compatible with E85
some guys around here are making great hp with them
I may put my chevelle on an E85 diet, but I still like the smell of racing fuel and we have a speedway that sells 110 leaded racing fuel for 5.99/gal
it,s your call. It can handle the compression and should run a little cooler also
