Time to buy a radiator for my 440 Dart

I`ve got a griffin 28x19- 1/1/4-2 row-crossflow, in my barracuda, the car fell off the floor jack and bent the radiator and front valence up about 1 1/4'. I straightened the valence and repainted it. the radiator is doing fine, no leaks. aprox. 700h.p., back up elec. cooling fan (in front) is set to come on at 200, it hasn't come on yet. 17" belt driven mech fan w/ shroud behing the rad.. was a universal ,had to relocate the mounting flanges. is about 4-5yrs old now, car is just finished.
when I bought this rad., they assured me it would cool 800 h.p., I don`t have 800 but it seems to work so far. to the op, 1 1/4 tubes will cool more than 1" tubes.
I also had a 3000 cfm elec. fan at one time , it wouldn`t keep my 505 cool .
