I have a few questions about E85. First, is it ok to run in a vehicle that isnt specifically set up for it? I have a 2003 Dodge Dakota with the V6 and 78 F150 with a 429. Will this fuel harm the Dodge with all its computers? Would it hurt the 429? I am about to rebuild the big block, is there anything to keep in mind for running this fuel when rebuilding it? Hardened valves seats, rings, etc. I am tired of lining these oil tycoons wallets while I go into the poorhouse at the pump every 3 days. Yeah, record profits in 2005 and the first quarter of 06....
