Carb says it is ethanol ready however I have my reservations. I did do new lines but have some rubber pieces I would replace first. As a fuel it's highly corrosive and I worry things like sending unit and even carb may not hold up heavy use. Friend of mine similar build and his car runs badly on ethanol. Same compression more cam than I with thunder down under heads on a 351 stroked. I would also need to replace fuel pump which I may do anyways. I think the bigger Carter or Holley would work well.
