Here's the Fan pics. This would be a great mod even for a Stock 350. I picked up a low mileage fan setup complete for $120 on eBay.
I trimmed the bottom down about 1/2" so that it was even with the ridge. Trim the top by the same amount the bottom was trimmed. I also had to remove the driver's side bottom mount; it interfered with the frame. You can see I trimmed the middle mount too. I had to notch the top on both sides to clear the top radiator supports. I cut off extensions on both the left and right side which left a hole, as you can see on the passenger side. I'll patch that later. Then I braced the bottom radiator support with 1/8" x 3" aluminum plate. Below that I mounted a 1/8" x 1.25" steel plate angle iron. That was mounted as to leave 3/8" clearance from the bottom radiator support. I stopped short of my winch control box on the passenger side. The extra wide portion of the bottom support circled in red matches up perfectly with the passenger side bottom mount on the fan shroud.
Later, I'll use a piece of sheet metal to complete the top mount. I'll clean up the cuts with some sandpaper; should look pretty factory when it's done, at least from the top. LOL
This works great! There'es a bit of space on the left and right side between the shroud and the radiator--about 3/8"--which I'll fill with heat resistant foam tape. Easy to put bolt up, easy to remove. Just slide the fan shroud down into the gap between the angle iron and the bottom radiator support, install bolts at top. Factory parts and lots of airflow.
