If you have no attic space above it, how do you plan to run the wire there in the first place? In a surfacee raceway on the ceiling? Sounds like you need a better location for your cooking zone. Like close to an exterior wall.

There is a soffit right above the stove where there is electrical already.

below the soffit there used to be cabinets with an under cabinet hood.

ive taken the cabinets and half the wall down, but have left the soffit due to all the electrical, gas, etc running through it. I'm going to hook the hood into the soffit which also has its duct work.
