I've took that post and I'm running I started building an 3.0L Ford(UK) Essex engine putting Ford(USA) 200cid pistons in it.but I'm still researching. I search anything about ethanol, bioethanol etc...but until I can make ethanol fuel cheaper than pump Gasoline I'm stuffed. Ethanol blends need to be as cheap as gas and do more MPG. E85 does but only at 10 to 1 plus and gasoline engines are typically 8.5 to 1 Drilling out the jets is bad but most carb manufacturers don't make +40% jets, I even asked. Injected engines are better at cold start. The best option would be use Sunoco E85-R Fuel unless you live in Minnesota and can get E98 mix it with 10% bio-diesel. Build the highest compression motor you can, get the most MPG and the most power.
