Electric of conventional engine fans
Yep I put one through the hood on a buddies Firebird 400 on a 1/4 pass 25 years ago. Not good!
Electric is nice, but they are noisy at an idel when they come on for the most part. Yes you gain a few ponnies. But I think all around the clutch type seems good for a street car.
Little more noise Vs a few HP maybe 5-7??
