Has anyone used the Wizard or ECP/Speedcooling radiators ?

Wizard - https://wizardcooling.com/1966-1969-26-b-b-mopar-applications-aluminum-radiator/

What has been your experience ? Quality , lifespan , actual cooling ?

I run a 505 BB , 650ish HP 11.0:1 . In a 1968 Plymouth Satellite . Currently using a AFCO radiator , temp sits 195/200 . This worked fine on my factory block 440 and 505 but the World block definately runs warmer . I run factory shroud , 5 blade clutch fan plus a manual control 14"elec pusher fan .
It looks like the Wizard/ECP has about 448 square inches surface are compared to about 427 sq" with the AFCO . So not sure if there is enough gained for the cost , i do have to import the radiator and pay in Aussie pesos .

Thanks in advance ,
