440 68 barracuda radiator fan fitment

The radiator is up against the cradle and it is 3 inches in width. Could I run a flat 17inch mechanical fan with an electric fan on the other side of the radiator?
Just now got back to this thread-----------
Thats what I`m doing, 17" mech. , and a 14" elec booster in front, set to come on at 205 , and off at 195. The 14' elec. has only been on once so far !
