Ok, I've got this idea for an ethanol engine. I've got this 360FE engine taking up space in my garage and am cooking up ideas for it. I wasn't sure if I should post this in the FE forum or the alternative fuel forum, but since the whole point would be to make an engine specifically for ethanol, I posted it here.

Anyway, here's how I would build it:

1. Custom pistons, zero deck, flat top with valve reliefs, 10cc valve reliefs.
2. Weld combustion chambers to reduce head combustion chamber volume, mill to make flat. Figure 50cc chambers by the time I'm done. Stock, unported heads.
3. .018" thick head gasket
4. Crane 343901 cam (260 / 272 degree dual pattern hydraulic)
5. Programmable fuel injection (I've already got it on my 390 that replaced the 360)
6. Headers, dual exhaust.

The ideas above as they relate to ethanol are as follows:
1. increase compression
2. increase compression
3. Achieve good quench for a fast burn to avoid detonation and increase efficiency, and to increase compression
4. Small cam to increase torque and mileage, and to increase dynamic compression
5. Allow precise fuel delivery

This would result in 12.73:1 compression. Desktop Dyno says it'll make plenty of power and torque with ethanol. (369hp @ 5000rpm, 474ft-lbs @ 2500rpm)

Anyone have any idea what kind of mileage it would get?

Again, this is just an idea. Any thoughts would be appreciated.
