Default My cheap E-Fan mod

I have been thinking of a way to put an electric fan on my truck for a couple of weeks now, but have been hampered by the removal of the stock fan. Well, I finally got that thing to loosen up last weekend, so I got to put my idea to the test.
I had an old e-fan laying around that I used on my old mud truck ('78 Bronco w/ 39.5 Swampers). I figured if it can cool off a 460 big block, why not the 5.4L...
I think I bought the fan from Summit Racing, it's a 16" metal blade driven by an electric motor. It had the highest CFM rating, which is why I bought it for the big block. The problem is it doesn't have a shroud, and I didn't want to mount it directly to the radiator...so I decided to mount it to the stock F150fan shroud.
To do this, I used a piece of 24" square sheet metal and cut it to use as a reducer. The fan is wired to a relay that is activated by a thermostatic switch or by the A/C.
I've attached a few pics so you guys can check it out, there's a few more of it installed in My Albums.
It has worked very well in the short time it's been on there. The temperature guage reads the same as it did with the stock fan. I'll have to wait and see what happens during the summer with the A/C full blast...it get's pretty hot here in Florida.
