(2) 12" fans versus (1) 16" fan

I dont know how much engine you got , but 2 12'' fans with more cfm than that wouldnt cool my 440/505 in a my 68 fastback. Depends on how ur engine is built and how much heat it produces --------
One 16'' wouldnt either !

If its adrag only car, u might get by with it ??View attachment 1715491892 View attachment 1715491894

Bob, it's a pretty livey 418, solid roller, 11:1...it will need a substantial cooling system. the 4 core radiator will help, but the more I study air flow requirements the more I see the need for more air moving across that radiator...
