It's all I've ran for the last 5 years. I've heard mixed reviews on the conversion kits. You may be money ahead and save yourself some headaches by selling your current carb and giving a true e85 carb guy a call. My current carb is a 1050 Dominator (venturi mod to flow 1150) from Eric at Horsepower Innovations. Awesome guy and great customer service. The pump stuff here in Nebraska varies from 70-85 depending on the time of year. I use Lucas ethanol additive and I haven't noticed any problems. Some winters I've pulled the carb, cleaned it, and stored it in the house. Other winters, like this year, I have just started the car about once a month and let it get up to temp. I love the fuel, but I also street drive mine a fair amount. You can't beat $1.50-$1.75 "race" gas.
