Anyone Run E-85?
I live up here in the north country and we have the E-85 all over. I've heard the octane is much higher. Does anyone use this with a higher compression engine? If so, any issues, likes dislikes etc. Thanks

I run it in my F100 with the FE 390. I originally designed the motor for premium pump gasoline, and it did that well. However, I had to pull timing to keep it from pinging. With the E85, it's never ran smoother, and I put all the timing back. It picked up a lot on the low end.
I do have a programmable Holley fuel injection system, which IMO made it easier to convert.
I am in the process of building a high compression E85 only motor, but it's not an FE. See here:

Did you have to replace any of your fuel lines or anything. I've heard some of the rubber products of older vehicles react with the E-85. Any issues? What are you running for compression? I am wondering because I just got a set of 406 heads last week and am thinking about building a 410 with them. So my compression will be around 10.5:1. Would be nice to be able to run the E-85. Cheaper, higher octane etc.

sure wish they'd hurry up and start poppin up some E85 stations out here my way in the east coast. My 390 likes to ping with the timing too so E85 would be great to have...especially since it's cheaper.

Actually the E-85 is more expensive due to the price of bulk Ethanol (which has it's own subsidies) but E-85 is heavily subsidized by your tax money to make it appear cheaper.

The compression ratio of my motor is somewhere around 9.7:1 to 10:1.
Eric, I fail to see why this is relevant. They wanted to know about running it in FE's. Leave the political discussion for the alternative fuels forum.
