I’m not sure which Griffin fan set up you had, but their “exact fit” electric fan combination only flows ~1730 CFM. Those are their numbers. It’s no where near enough CFM to be a standalone electric fan on a street driven A-body with decent horsepower.
An electric fan is just one part of the cooling system, and just because parts are expensive doesn’t mean they’re a good fit for every application. There’s no way I’d bother with trying to use an electric fan that flows less than 2,500 CFM for the way I use my car. Maybe in a colder climate, or for a car that never sees traffic etc it might be ok, but it certainly wouldn’t hold up to getting stuck in traffic in 100°+ weather. My cheap reproduction Contour fans managed that easily. But they flow 3k CFM on the low speed, and close to 5k CFM on the high speed.
