I was looking at converting to E85 eventually but was wondering if a mix would work. Instead of using race fuel @8 bucks a gallon, what about 105 octain E85 and 93 with the existing carbs? Im sure the jet sizes would have to go up if I was going to the track but what about street duty? 1957 Power wagon wm300 original 10.000 mile truck, 1964 dodge Polara Convertible numbers matching

If it is a 426 Gen II hemi, the octane will need to be higher than a new style Gen III . This program will require testing and buying fuel in bulk, to keep the mixture consistent. The change in octane is linear meaning at 50/50 you get the average of the two 25/75 you get a 25 percent boost in octane. How much cranking compression you have will also play a big part in all this. Better give some specs to us, to help determine what will work. It might be much simpler to buy 93 octane and mix it with race fuel. It might not take a very strong mixture to get you where you need to be. If your cam is fairly tame, a cam change may be a good option as well. More top end power, less octane needed.

I dont know of anyone using AFBs with e-85 but if you mix its gonna be lean if you dont adjust for the e-85.. in a normal e-85 application you would run 30% more fuel to be equal to gas

I think any carb. can be converted to E85 by a good carb. guy, the real concern is if you ever want to go back to pump gas and have the original carbs. converted back to gas. I would buy a set of E85 carbs for E85 and save the other ones for later, especially if thier the correct part numbers for that year motor BTW, I don't think any late or current made Holleys will fit on a stock Street Hemi 2x4 intake Mr.Cab Racing and winning with Mopars since 1964.

Perhaps I will look into a set of carbs and keep my original just in case. But I will convert my single carb 440 dart to E85.

The first 2 years I mixed my own.I bought 2 55 gallon barrels of E98 and found a gas station that sold non alcohol gas. Making the right mixture was easy. I just marked a gallon jug and added the E85 to the gas and 95% of time it was dead on E85 or E86. Now there are gas stations close and yes I buy it from a gas station. The steel drums from the E98 are used. I take a test right at the pumps before I fill. The best part I still have E98 stored in a small contaner so if the blend is weak I can jack it up. I can tell you it does not take much to change the blend. If the MODS did their job I would not be hitting the notify MOD button. LOL

Also ethanol DOESNT mix well with leaded fuels. And it will clean all the old dirt and varnish in a used tank/fuel lines, it will end up inthe carbs.

If the motor only needs a moderate octane increase, it may be possible to come up with a mix that the carbs can handle as is. If the fuel is blended to make something like E40, it should have about 96 octane, and only require a jet change of a few steps to correct the fuel mixture. With dual carbs which are not maxed out for air and fuel flow at WOT, it might be very possible. One trip to a chassis dyno with a couple of carb tuning kits and a fresh load of mixed fuel ought to tell the tale. I am considering this for my 5.7 stroker street motor.
