I'd have to go look, but one of the carb companies in the National Dragster is advertising a 75/25 Gas/Alcohol carb. It's a matter of getting the metering correct. 10% is probably within the jet capabilities of most Holly carbs. Also less issue with the corrosive properties of methanol and no need for top oil additive. I have considered this myself, but haven't tried it yet. Too many other irons in the fire....
