Pretty sure the ZR1 makes noticeably more torque than the GT500 by close to 100 lb-ft if I remember correctly. Also what compression are both motors running? That would make a noticeable difference.
GM typically sets up their motors to have a broader and more linear powerband compared to the Coyote based motors even though I'm sure the GT500 motor is pretty strong most everywhere. Just like with an LSx the GEN5 motors personality is easily manipulated by a cam swap.

according to the google machine
LT 5 is 10:1 compression ratio, the predator is 9.5:1
The LT5 makes 90 more FT/Lbs of torque
The predator makes 625 ft/lbs from 3k-7500
