So what are the reccomendations to run E85 with a 13.5 CR 512 stroker motor. Is it possible to run the pump E85 fuel or is it easier on the engine to buy VP E85.

What kind of changes need to be made. The dominator was done by Pro Systems for gasoline before so Ill send that off the Patrick for recalibration.

What about fuel pumps and other seals / hose in the system.

I know the car will run cooler so that will be a plus any other comments.....

13.5 is just fine for the switch, just make sure your fuel system can deliver 30% more fuel than you would need with gasoline. Ethanol won't destroy rubber hoses as methanol would.
i'll be switching to e85 next year too, and already have the Dom carb converted...13.5 540 with way too small 440-1 heads.
around here, e85 is $4.50/gal. cheaper than race 110. and even with the 30% increase in fuel demand factored in, the money saved will add up quickly. like you say, the motor will run cooler too. it's a no brainer

Mr Pbody should chime in with some good advice...

This was my second year running E85. 2008 with a carb, and 2009 with the Ron's Flying Toilet mechanical injection. I love it. Runs great, cheapest hot rod fuel around. It is slightly cheaper than pump 87 octane gas.

My Combo:

4.250" stroke, 4.375" bore, 511 CID in a low deck 400 block
Indy 440-1 heads, 68cc, giving 13.5 CR
Indy 400-3 intake (single 4-barrel dominator)
Comp Cams solid lifter MM305S-10, 279/287, 0.650"/0.630", 110 LSA
2-1/8" x 32" x 4" collector headers

I only use summer grade E85, 82-85% ethanol. Ask the station owner for the delivery sheet to make sure the ethanol to gas percentage is right. Avoid the winter grade which could be as low as 70-75% (suitable for lower CR); and will also change the tune up needed.

You will need to deliver about 30% more fuel than gasoline, so make sure your system is up to it. Check this forum:

on tip i give is to find your source for E85 and stick with that source. or test your content often. i just bought a drum so that i'll have enough to last. also i take plenty with me to the track.. if you are going out of town and not sure you brought enough for the long weekend research available stations before you leave.
i was told about this website and even seen it in a post on this site. it offers alot of good info.

the guy that did my carb has done many e85 setups around here if you'd like his number pm me.

So how much E85 does it take to feed a 512 that made 700hp on the dyno. Carb is a 9375 Dominator.

How muc pump do you recommend and how big of a fuel line?

Thanks for the links and advice.

Thanks for the info Mr P body.

I am wondering how much this fuel will vary at the pump in the summer here in Illinois? I have seen a few testing kits for the fuel content or something like that.

Does anyone have experience testing the E85?

One last question for now on the tune up for E85.

What heat range plug and total timing #s.

My distributor is locked.

seems like a good site.

and www.e85performance.net

I going to switch this winter ..trying learn all I can,

Jim, can you explain the proper procedure on how to do the test? And how much is the te$t kit?

Looks like Quick Fuel Technology is selling a kit here:
