Ethanol carburetor

[Highbanked Hauler]

   Is it much of a job to set up a carburetor  to run on ethanol ??

I would suggest you contact Quickfuels Technology or Promax Carburetors, they have a very good description & cure for the problems associated with them... or even Holley.... Ethanol requires larger passages, better flowing Metering Blocks &/or Plates, different air bleeds, larger jets, no rubber &/or non-anodized aluminum in the system, larger accel. pumps, cams & discharge nozzles amongst other improvements... for every % of Ethanol or any alcohol product, you will need 170% more volume of fuel flow & delivery...

You have some good info on E85 and carbs here:

Thanks, that is good information as I am ignorant  about alcohol fuel performance.. A few years ago son and I took the Challenger for  a rocket ride out to the west coast and we got a couple of tanks of E85 in the mid west and maybe it was my imagination but the car seemed to run "smoother".

It probably leaned it out some {I always remember the saying "lean is mean", until she blows} & it has a higher octane count too, but it also has corrosive properties also, you will need to add a top cylinder lubricant, like Lucas fuel treatment or Stabil &/or some type of water separator/rust prohibitive additive, because of condensation from the alcohol content...

There is a lot of myths circulating regarding E85 in older engines and fuel systems...most of it seems to be just that...myths.

  So according to the question and answer you don't have to replace "rubber" hoses. Would that be the same for the fuel pump also ?

The stuff I mentioned isn't a myth when you get hoses rotting from the inside out, rubber o-rings rotting away & get white crystal forming on aluminum.... I'm just saying, believe what ever you want... Allot of the new rubber products aren't really pure rubber any longer either... Happy Moparing

Point taken, when I get into something I am not familiar with I first ask and then use caution.  From one of those links I did learn there is quite a difference between  Ethanol and  Methanol which is really rude corrosion wise.  I am a long ways off of driving this thing anyway. This 440 is supposed to have 12-1 compression which I question as I have the timing 12 advanced and when I floor it there is no pinging or hammering from it with 92 in it.

Yes Methanol is far more corrosive, but all alcohols are to some degree & Methanol {wood grain alcohol/racing fuels} is a different subject all together, it has some serious power benefits also, when tuned & maintained properly...
