I have in another topic the problem i am having affording race gas on the streets in my Dart, one idea was to turn my motor into pump gas another just convert to E85.
I want to hear dyno #'s or track times from those guys that have tried this conversion......
was it worth it?
did you drop off allot ?
Thanks, Tim

Your system need to pump at least 30% more volume over
gas... I use the same pump(pumps in my case, 2 Holley
black 150's) and a 4 port Mallory return style reg,
all these were used on my 1050 dom on my race gas
set up then I changed to a 1050 dom on E-85

An easy YES Race gas $9.25/gallon, E85 $2.29/gallon. That pays for the conversion in short order. And E85 runs a little cooler. I changed more than just the carb, so my ET is not a direct fuel comparison. I estimate the E85 was 0.15 faster than gas, and methanol was another 0.15 faster than E85 in hot summer weather. The differences get smaller in colder air.

Now you've hot me thinking about it...Does anyone know if Holley 2300, 2-barrel sixpack carbs can be modified to have enough fuel flow capacity to run E85 and feed nearly 700 hp?
1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's
1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

I dont see why not... your increasing the amount of
fuel not the air so if you have enough air flow you
would just need to increase the fuel volume by 30%
across the board... I dealt with Quick Fuel so you
might talk to them

Thanks for the tip. I found a 500 CFM E85 2bbl that's used for circle track racing on their website. It looks like with a little modification to the top of the carb it would be a bolt on replacement. It sure would be nice to have a trio of 500CFM E85 carbs under my shaker. I'm going to have to give them a call tomorrow to see how much that would set me back, and if they think it can be made to work on my application.

Mr Peabody should i do the volume check first with gas and then figure from that? Brad
Really you need to figure your engine consumption
as it is now then figure 30% more and see if your fuel
system will do at least that much

Is there a problem with E85 ruining oil like is the case with methanol? S/F....Ken M
No its nothing like meth... get get it warmed up
before your run... I get to about 185 degrees at the
end of my run each time and when I get back to my pit
spot and shut it down it back to about 165... I havent
seen hardly any oil contamination, I went last season
with 1 oil change mid season and it still looked good

or winterblends?
