well im thinking of running the new motor on e85 and was wondering what needs to be done with the carb? im going to rebilld it anyways. its a deamon carb if it matters...

and yes i will be useing all new fuel lines and such, and my fuel pump is capitable with ackhool(i cant spell tonight).
 
needs to be anodized or else itll corrode. its a pain. better off selling it and buying an alky carb
 
Don't do it that stuffs soooooooooooooooooo coresive it will eat your fuel system then leak on your car and eat it too...




But no seriously its fine without anodized stuff, most of the jargo from the internet or "felix and the gang" as my friends Dad call it haha is bullshit that they are commenting on with NO real world experience. Typical of what most engineers do with book info thinking its always correct
 
Intake and exhaust valves will wear much more quickly with E85 unless your valves and seats are designed for E85.
 
my current day job is designing valves for OEM engines (used to be a brake engineer). I have done several E85 compatible valve designs. I have seen a number of "regular" valves after running tests with E85, and in general, they aren't pretty at all. But, to be fair, the tests are for high mileage. For someone modding thier own car, its not necessarily a deal breaker, just something to keep tabs on, and know you may have to tear the heads down to replace the valves and seats much much sooner than you normally would. Honestly its not too terribly different in concept from the switch from leaded to unleaded fuel years ago.
 
Something to consider is just where you can get E85 now. I was running my car last year on it. Found out I needed to make some changes, so I did a bit of work, now that its time to run again, the stations around my house no longer have E85....
Maybe someone finally realized that it was/is a waste of time to try & run. Its good for race fuel replacement, but thats about it.
 
lots of myth in here....i know lots of people that run carbed e85 setups without any problems....and they've had their same setups for years in cars that didnt have optimum setups. Get some E85 metering blocks from quickfuel and you'll be fine....the stuff isnt as corrosive as people make it out to be...now methanol is a different story....

another thing E85 acts like a solvent so it willclean out a lot of gunk thats accumulated in your gas tank and lines so you will probably need new fuel filters
