electric fan on a 22''champion rad

I run same set up on my dart, 360 motor never gets over 180 with a 160 thermostat in it, not sure whats wrong with yours, but no issues here!!!!!!!! quick question just popped in mine here, my radiator is also a 4 row and i put my fan on front of radiator instead of engine compartment because with my March Pulleys there was no room for a fan, also i run a Hi-Po water pump!!!!
