Stronger bite force alligator or crocodile?

a crocs bite is quite a bit stronger (20% I think) to a comparative gator. because of the crocs more narrow snout it has less surface area then an alligator.

This may also be true not only because of surface area but because crocodiles can more easily dish out more energy at any given moment due to the fact that they have a four-chambered heart which operates much more efficiently than an alligator's three-chambered heart. (this is also why alligators seem less agile and less aggressive, they just don't have the ability to function with efficiency when blood flows too quickly through the heart.
