FlexFuel Conversion for 99 Tahoe

I was wondering if anybody knew about a E85/Flex fuel conversion kit for a 99 tahoe. I am planning a serious cross-counry road trip in June/July and gas prices are expected to be enormous. I have noticed here in Colorado, E85 is way cheaper and I will be driving through Nebraska and Iowa (BIG CORN PRODUCERS) and figured it might help on the gas bill.

It will be cheaper to sell your Tahoe and buy an E85 Tahoe. The conversion requires internal engine changes, fuel management changes and fuel tank/fuel lines to be changed.
