i have a friend who wants to build a 428 to run on E-85. i would like for him to talk to somebody running E-85 in a street car befor he does the build.

from what i have read EFI will better for ease of tunning. with flat top pistons 12 to 1 with 60cc heads that way if E-85 doesn't work out he can just change to a set of 72 cc eddy heads and run pump gas at 10.5 to 1.

Here's my problem with E-85.. BTU content is not there, so MPG and power both go down.

From ASK encyclopedia;

Ethanol and Fuels Like E85 [edit]
1.5 gallons of ethanol has the same energy content as 1.0 gallon of gasoline.

The energy content of 1.0 US gallon of ethanol is 76,100 BTU, compared to 114,100 BTU for gasoline. (see chart above)

A flex-fuel vehicle may experience as much as 25% lower MPG when using E85 (85% ethanol) products. This is in part because the engine's compression ratio is fixed mechanically and electronic sensors can only modify the timing of the spark and/or instruct the fuel injection system to provide more of the reduced energy-content fuel.[

hello REOWSLEY

There is a guy here that did just that with a 14:1 engine. He posted videos. it is now done and running on the street. he had the contact info for his machine shop in his posts and possibly tuffnuff can forward a post directly to his email since he has not posted on the site for a while.

here is one of his threads. the giy in the video in the thread says what his shop name is. he can also contact the guy. he is doing exactly what your friend wants to try. the members name is Aguila1
