With the high price of racing fuel, especially the normal alchohol that circle track cars run, there's lots of talk about this on the racing forums right now. Check out the powertrain tech section at www.4m.net for starters.
Basically from what I read the E-85 is about halfway between the high octane race gas and the methanol that they have been running. Higher compression would help up to a point, dont go overboard. And the carb has to be reworked to flow more fuel than a gas carb, although not as much as a regular alchohol carb. Lots of the specialty carb builders such as Braswell, Barry Grant, etc are now offering custom built E-85 racing carbs. Fuel injection would probably work fine as long as you had a way to adjust the amount of fuel going through it(sensors on the exhaust hooked to laptop computer which was hooked to vehicle computer to tune it).
PS-if you're serious about making power on a small block chevy, forget about the 305 heads unless you're really on a budget and/or already have a set. They're thin-walled castings prone to cracking, and by the time you get 'em ported, install larger valves, etc, you'll have spent almost the same amount of money that you would have to buy a brand new set of small chamber Dart or World Products heads. The GM Vortech heads that came on pickup motors are well worth the money however.

The gentleman no longer farmed because the entire area was developed with housing and light industry. I had stopped several times and knocked on the door but no one would answer. My curiosity was up and I wanted to contact the owner. I wanted to see what he planned to do with the combine.
