Well with E-85 you burn 30% more fuel than gas so if your tank is large enough it wouldnt be any problem... yes you can run a alky carb IF you reduce all of the circuits down to the E-85 values(alky is about 2 times that of gas)... on compression you can get away with way more compression... I am at 14.1:1 on E-85... I would go with about 12.5 on the street just in case... I was going to build my Rampage for E-85 but if I go out of state they might not have E-85 so I went with pump gas instead
