Blown alcohol small block?

Alcohol adds just a few things to your race prep and helps a few. Where I get my 54 gallon barrel of alcohol it comes with upper end lube already added for 165 dollars a drum. I rebuild my carb before each race season giving it a good cleaning and flush. I change out my floats every two years. I never start my engine like some guys do and rev it up to empress my friends. COLD starts make WATER. On race day I unload and when they call the class before me I drive around getting it up to at least 180 degrees using my lean out valve. My lean out valve is a simple 1/2 inch ball-valve plumbed into either my carb, carb spacer, or back of my intake manifold. Open it up, lean it out and build heat. After a pass I pick up my time slip, shut off my electric water pump, fan, and build heat driving back to my pit spot. I never have to run my pump or fan in the pits to cool the engine. This heat helps burn off any moisture that would come from running cool. I found Brad Penn oil (now Penn Grade) is a great oil for alcohol. Racing almost every weekend like I do I could probably get away with two oil changes a season but usually do it 3 times so I can check the oil filter. With alcohol HEAT is your friend not your enemy. Rich jetting POLLUTES the oil so an EGT readout really helps getting your jetting right.
Couple questions I have. Do you use a primer system for cool weather starting.
I recently was reading an article in dragzine and the racer was saying that after a run he plugs in an engine oil heater. He claims that when the oil was at a certain temperature that it burned off the alcohol from the engine oil. Have you heard of that?
What type of floats do you use that you are changing out.
Can you elaborate on your fuel system materials type of fuel pump,
Fuel cell material etc. what do you do at the end of the season?
I have heard some people say they pickle their system with gasoline. You also mentioned in another thread that you must use an exhaust system that exits out from under the car because of the poisonous fumes.
