Thinking of going to E85 on the Dart
E85 has a lower BTU rating, therefore more fuel must be burned to make the same power, you fuel system will need to supply about 30% more fuel.
the carb will need to be rejetted...Quick Fuel Technology make a kit with new metering blocks, also..you will need new steel needle n seats in carb plus larger squirter...
if you google racing with e85 you will find a ton of info...
I am changing over because of the cost of the fuel...e85 is easy to get here....I race two cars so the fuel cost is high...and I bought two new QF E85 950 DP carbs...LOL
