My mechanical fan was sitting too low and not performing well enough ... I have a 350 sbc, too ... but didn't need a shroud with the electric fan I put in my truck.

If you're using a 16-inch fan, I suggest you use Two Relays -- See Here

I also believe in using a Fusible Link instead of a circuit breaker (and definitely NOT a fuse).
