Started new E-85 topic from the "EFI for stock 440" thread.

Anyhow, Here is what I was thinking:
In theory, comparing 1000 cfm air flow (my carb size) on E-85 and Gasoline.
The data listed was just from a quick internet search, but this these are the values I found for the various conversions:
A pound of air is about 13.15 cubic/feet (normal temp/sea-level conditions?)
so 1000 cfm would be about 76.0456 pounds of air a minute?
I divided that by the air/fuel ratio to get pounds of fuel/minute using the 116090 for gas and 84250 for E-85?
This gave me 5.173 pounds of fuel/minute on gasoline, and 7.839 pounds on E-85.
Converting the pounds to gallons using 6.2 pounds/gallon gasoline and 6.59 for E-85 I get 0.834 gallon of gas and 1.189 gallons E-85?
I then multiplied the gallons of fuel by their BTU and got 96,863 BTU (per minute) on Gasoline, and 100,227 BTU on E-85?
So it looks like the E-85 has about 3.3% more BTU for an equal amount of airflow? This ignores the octane and cooling effects.

I have read that E-85 is supposed to be about 5% more power overall?
