Converting to methanol
Discussion
I am looking into running methanol insted of prtrol next year in my 69 camaro and I wondered if anyone else had done it and could give me any advice.
I know that you need to use about 30% more than petrol so I have to make sure that the fuel pump can handle it. I have been told that I will also have to re jet my carb (1050 dominator) How easy is this ?

These are fundamental questions and there's a lot more to think about. It is unlikely that rejetting your carb will work. It isn't just a case of putting in double sized main jets but you'll need to worry about the metering and the pump shots will need to be about double that of gasoline.
The fuel pump, it's output volume and pressure is critical to tuning an Alky setup, if you get it wrong you'll either lean out the motor and break it or you'll run too rich and go slowly. Methanol is a deadly poison which can be absorbed through your skin and, if you leave it to evaporate, it will form crystals which will make a nice mess of your fuel system.
Petrol is about 70% more potent than methanol but you can burn about twice as much methanol than you can petrol - that's where the power comes from. However, you have to get it right.

You'll have read by now that you need to get rid of all of the rubber in the fuel system, as the ethanol eats it for breakfast.
Running dirt race car engines on Methanol is pretty simple - you can get a carb ready jetted for alcohol off the shelf. Change the lines for stainless.
If you don't change your carb for an alcohol ready one - make sure your floats are alcohol safe.
I would assume that E85 is pretty much the same - just that it starts easier having a snifter of guzzoline in it - so you don't need the can of easystart handy quite as much.
