are you having any trouble with it overheating or heating up at idle. the shroud makes the fan pull air through the radiator at idle, when driving the air is pushed through the radiator by force of your forward movement. if its not heating up why fix it, unless your going for the original look.

> if its not heating up why fix it
Because if it throws a fan blade it can easily kill you the same as if you leaned on the fan by accident while it was running while setting the timing. Mine threw a blade about a year ago and did some damage, not to mention it vibrated my water pump to death by the time I got it home, but, that is another story.

My 71 F350 has what looks like a factory fiber shroud on it. Of course it is cracked and has a part of it missing.

My son's '72 360 C-6 automatic with factory A/C had a fan shroud. The fan also had a fan clutch.
It was made of stamped metal, but was quite narrow. The fan just barely sat inside the rim.
I put a fiberglass shroud on my '66 F-100, I took it off a '76 and it fit perfectly.
I also use a '76 fan clutch and fan on my '66 352 instead of the old spacer and the 4 bladed fan.

if your looking for a shroud, i know that 66-79 all had a radiator(cuc #433/444) on v8's so any of these fan shrouds should work for you, i just found a mint shourd off a '79 that i put on my 68 250 390, they are all fairly interchangeable

No, they won't stop a fan blade. I have seen a blade come off, go through the shroud, and then through the hood. The only reason for the top shroud of the early 70's was to keep you from putting your hand into the fan while the engine was running. Later full shrouds helped with cooling.

A fiberglass shroud will most certainly stop or deflect a fan blade. A lot of it depends at which speed it lets go. Obviously at idle it stands a much better chance. If you lose one at almost 3,000 rpms like I did, it will shoot right through just about anything. I got lucky and mine even missed my hose, put a dent in the inner fender and hood, and then I drove over it.

When I lost a steel fan blade on my 3208 Cat in a Louisville some how nothing had a mark on it. I have never been able to figure that one out. I replaced it with a fiberglass fan just to be safer.
