I've run a 1000mm tall, 500mm wide delta with 50oz.in motors without problem.
It doesn't take that much effort to move the effector, notice that all three motors support the weight of the effector even while powered off. Higher torque will allow you to move faster and I highly recommend 76oz.in. for large format printers, but it's not required.
By the way, I would recommend putting the motors in the bottom since you have the room.
Not just for the wasted space, but you will have less wiring hassle (2 wires per end stop per tower rather than 4 wires per motor) but also, the top is less supported and that extra weight can make it swing like a pendulum when the effector gets moving. This is especially a problem since you are just using smooth rod, which doesn't really build a sturdy frame, and with your tiny clamps, it will be even less sturdy.
Looks good though.
