What kind of motor do you have?
A slant can get away with a much wimpier fan than a stroked 360.
I run a 17" thermostatic controlled fan in my car, set up fully automatic and it works great.
When I change to the 360 Mag I'll have to change it out for a fan clutch setup because the electric won't keep up.
I have seen built V8's run 2 hi speed electrics with a shroud and get away with it.
