Al's right Methanol is what you want to use, I have used both VP and the stuff from the local chemical company and haven't noticed a difference except price.
There are a couple of things to consider while it's half the cost of racing gas you will use twice as much. It's a great solvent and will attack any un-anodized aluminum and some rubber hoses. your fuel system (pump and lines) needs to deliver more fuel.
You need to have bronze valve guides as the methanol will wash the oil off of them and the cast iron ones don't last too long.
I also run scented top oil (lube) for valve guide life and because it doesn't smell great.
I have always run it with one of Ron's fuel Injection systems they are simple and offer instant throttle response I have seen good and bad in alchol carbs.
It will make the car vary less with weather changes (more consistent)and with fuel injection the car will be a little faster but it will be harder to start especially if the temperature drops below ~60F.and it will take longer to heat up and if you don't have a vacumn pump the oil will look like snot and need to be changed more frequently.
Sincerely
