What is the voltage driving the 40a? if it is low like 12v, then look to the automotive world for gizmos like below. Depending on the driving voltage, you should be able to make a shunt that would be optimized for the power that will be disipated and still with a decent measurable voltage drop across it. Also, what is the gizmo thru which the current is to flow (assuming you are not doing a dead short smoke test)?
