    What disadvantages if any does the flex fuel motor have over a regular 5.3 when it comes time to install heads and a cam or nitrous and other types of forced induction? I can't imagine there being that big of a difference between the two.

    Yep. Basicly they flow more fuel. They have to flow more of the flex fuel to perform like it does on normal fuel. But what is normal fuel anymore with all the mixes they have now.

    Usually its some kind of ethanol/corn mash brew mixed with the normal gasoline to dilute it but raise the octane. I think they typically call it E85 or something like that.

    Check this out....http://www.gm.com/company/onlygm/fuel_flexible.html

    E85 FlexFuel Vehicles operate on a blend of 85% ethanol and 15% gasoline. Good news, because for every 37 gallons of E85 ethanol used, you&#39;re saving one barrel of oil-- reducing our dependence on petroleum. E85 ethanol, a renewable fuel made from U.S. grown bio material (like corn or grain products), also helps reduce greenhouse gas emissions. GM has more than 1.5 million FlexFuel Vehicles on the road today in all 50 states. Together we can:

    Take advantage of the choice between gas-powered vehicles and cleaner, E85 ethanol vehicles
    Reduce our dependence on petroleum
    Reduce carbon dioxide emissions
    Gain increased horsepower for better engine performance because E85 ethanol fuel has a higher octane rating than premium gasoline
    Lessen engine wear

    Ya I found they have different mixes around the nation. Some are suppose to help lower emissions.

    E85 would also keep people that depend on farming with a job. Farming is 95% of the work around here.. I feel bad for them lately with fuel going outrageous and the crops not bringing anything. I liked being a farm hand, but I&#39;d never own one.

    Anyone know if the E85 is available in all states yet?
