When I raced my 360 with 12/1 compression. I never had a problem with running out if fuel unless I forgot to turn on the electric pump If I forgot to turn it on. I would run out of gas around 800'. I loved the mechanical/electric combo. Never had a problem starting the engine. Just let the electric fill the carb and pump the gas and it started. That engine in my 2900 pound car ran 11.0's.
Now I have a street motor in it and it runs 12.0's with 3.23's in the back. A real street car weighing about 3300 lbs that I can drive to the strip, race and drive home. My 76 year old body is done racing. I need to sell the car before I meet my maker.

If you have any interest, I will send pictures with a detailed description
