Blown alcohol small block?
Most guys around here running dirt late models run moonshine.... You may need a squirt of gas to life the fire on cold nights.
Some guys have a carb drain that replaces one fuel bowl bolt. They drain the carbs after each show. I've seen a t fitting installed in a fuel line hooked to a one quart tank that holds gasoline for starting.
A magnetic heater stuck to the oil pan will help to keep the oil clean.
Use Dino oil or a blend but not synthetic. A Pennsylvania based oil is best for alky...Brad Penn, Schaeffer, the new stuff from Joe Gibbs or CenPeCo are all good.
I'll be running alky in my small block dirt car.
