OK- this may be a no-brainer, but- With regular gas now at $4.15 a gallon (and Rising), I can get E85 for $3.29. My current set-up is the following- 318- stock block/oiling. 97 Iron Magnum heads- compression ratio in the 9.5-9.8 range. Eddy Air-gap intake. Carter AVS (340 spec) 1970-1 vintage- rebuilt and running well on gas. Factory Mechanical fuel pump backed up with Carter Electric pump and Fram can-style filter. I have a Holley Regulator, but haven't needed it. New steel fuel lines through-out. Braided hose for transitions from Pump to carb and modern rubber hose from tank to pump.
Now- I know that there are problems with E85 and Aluminum and the rubber in fuel lines. I can find NOTHING on the Edelbrock/Carter/Federal Mogul websites that tells me if I'm OK with the Electric Pump- it's the old-style gerotor pump they have been making for decades- or the carb.
So- before I go melting things- what's the opinion on here as to whether this is going to work? I know I'll be changing the jetting and needles and upping the fuel pressure a bit to comensate for the E85. But that's about it.
Any feedback would be appreciated.

Do some more research. There are several websites dedicated to this exact topic.
This is for an eddie carb, not carter..

I know turboforums has tons of info but typically with regards to boosted applications.
I can tell you that it takes 30% more E85 than pump gas, typically for the same results.
I do know E85 has an octane rating of 105.
There are also several folks on the mustang forums cutting it in with pump gas 87 octane at 9:1 ratio and jacking up their timing to get the performance they need.

I don't think it will work unless you're really hard headed and have time and money to burn.
Edelbrock tried to develop a line of E85 carbs and after a couple of years they gave up. They have a lot of resources including engineers, dyno rooms, technicians, etc. and they couldn't make it happen.
Considering how well the performer 750 works I'm not surprised ...
I was hoping to be able to switch a carter over to E85 use but it doesn't seem like a worthwhile venture .

The link provided shows that they will do a working E85 conversion on the Eddy carbs, but it is EXPENSIVE. And once done- you cannot convert it back again. Not really something I want to do to a 1970-1971 vintage carb. I really, really hate Holleys, but in this case it would be easier/cheaper to buy a used 4150 and have it converted. My main concern was if the fuel would eat the aluminum housing of the carb- but apparently that is a non-issue. Might be worth a shot.... I went to the 1/2 fuel line when I re-plumbed everything (wanted to be able to do a big-block conversion in the future), and the pump should be OK...... Hmmmmmmmmmmmm CC.

I was considering it when E85 was about 1/2 of E10 or non E10 regular (here in Lincoln) & yes the (web) sites have alot of critical info. IIRC want very high SCR to take full adv of it plus carb mods and prob more mods but now that it's within a buck or so of regular I got off it as w a complete rebuild of that order, the money I'd put into it it'll take alot of time/miles to get ahead.
