I'm assuming you'd be renting a "B" model with 180 H.P.
It's useful load with the standard 50 gallon tanks is usually about 150 lbs. more than a Hawk. Cardinals are well built and thus have heavy airframes. If it has the 60 gallon optional tanks, you shouldn't need to fill them anyway.
If you're talking about the 150 H.P. Cardinals of 1968 vintage, you'd be better of with a Skyhawk. The 150 H.P. Cardinal is a hopeless dog at gross weight. Avoid it.
