Time to buy a radiator for my 440 Dart

I would recommend AGAINST a Griffin radiator. about 8 years ago I paid $1000 for one of their perfect fit radiators. It does look very nice, but it worked no better than the stock 2 row standard radiator the car came with. It is supposedly good for 600 HP, but it barely cools my 375 HP 340.
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.
