Electric fans and shroud recommendations

Getting ready to buy some more parts for my 70 dart stroker big block drag car, maybe later some street
I am going to buy a 26 in 2 core 1.25 tube cold case radiator.
I'm looking for a fan or fans and shroud efficient enough to cool what maybe close to mid 600 horsepower.
Let me know what you run, how you like it & anything you might think is better
Thank you all.
Wizard radiator with (2) 1 1/4 cores with a front mounted Spal electric fan and a fan mount that they welded to the radiator. Zero cooling issues in an over 970hp small block.
