e85
is it possible to run e85 on a stock 350 for a 70-72 C3? - is it possible to make so modifications so you could? - 105 octane at the pump is pretty tempting....!!! - thanks, ed

My mistake!! I guess I am half alseep in this computer chair. E85 would be 85% ethanol and 15% gasoline. You are correct, it would attack the lines, gaskets, and most likely many metal parts. I stand corrected. Shoot, I even sit corrected!!

Some say you need this and that who knows ,Ive seen tests of e85 in a Suburban on youtube that showed it to run well and even disassembeld the motor and tank to show if any harm was done,
but who knows if thats a bogus clip.
You need to jet up on the carb because e85 is less efficient so you burn more fuel.

(1) Because, when setup properly, an E85 motor will make more power than a gas engine.
(2) Because, when tuned correctly, an E85 engine stays cleaner inside than a gas engine.
(3) Because E85 is cheaper than premium (for now).
(4) Because it means we can get away from buying oil from our peace loving Arab friends.

I wasn't questioning the benefits of E85, I was just questioning why the fuel system would need to be upgraded. Now I understand. I see nothing wrong with E85.

That is correct.. Edelbrock had an E85 600 CFM carb in the works and was suppose to be available last April. I wonder what happened...

TSW - that is the website that got me thinking about all of this...back to FRS's point - why wouldn't this be like 103 racing fuel - I mean...I am not saying it isn't ... just want to understand ...one answer might be that ethanol does not contain the same energy per unit as gasoline - but what does octane do? - given that ethanol has 105, does that mean more hp but less efficiency? - and can anyone confirm that apart from increased aggressiveness to rubber, that it is corrosive to metal? - thanks!! - ed

The only two downsides are its lower energy content and its latent heat of vaporization. The second one is why they mix it with gasoline. In the winter E85 would become E70.

you don't get something for nothing
Only rather recent & Very limited Ethanol fueled Indy & Sprints ... for 40+ years & until recently they'd all run on Methanol ... AFAIK, only IRL has gone totally Ethanol. Methanol & Ethanol similar alcohols but different.
Methanol = CH3-OH (drink & die)
Ethanol = C2H5-OH (drinkable)
Both are corrosive ... alky race cars require & have fuel systems designed for alky ... doubt much long-term success w/ any old gas car running hi% of any alky. Once you did get it worked out, you'd be filling ALOT more often than w/gas ... you'll use alot more alky /mile ... same true for current E85 crappy mileage.
Rant: Friends ... please don't fall for nor offer your tax $ to CORN-based ethanol boondoggle. Alky can help our short-term fuel thirst, but corn is not the wisest rawstock for a chemical process ... corn is best-used as food.

Not only would you have to stop for refueling more often per mile it will end up costing more to drive if we adopted this as an alternate fuel strategy. The economics are not favorable as a significant source of alternative fuel. We would have to see a huge change in the way people feed themselves not to mention that corn has to be cultivated and processed before we can refine it into fuel which adds to the cost. We don't have anywhere near the amount of excess corn available to significantly impact the reliance on fossil fuels. There needs to be another solution.-Mark.
