Fan shroud - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Did all 67-72 trucks come with a fan shroud? Mine does not have one and never according to my dad who daily drove this truck for 30 years. I am about 90% complete on my restoration and just bought a new radiator and figured I would see if I should get a shroud also. I assume it could only help cooling. The truck is a non AC with a 350 three on the tree.

I believe all V8s had shrouds. Your engine is likely in the forward mount 2WD V8 position. 4WD V8s had their SBCs in the rearward mounts, so the shroud is deeper. I have the 4WD shroud since the previous owner had swapped out the I6 and mounted a V8 in the back 4WD position, which kept the exhaust and driveshaft the same as before.

There are AC and non-AC shrouds, but I think AC shrouds may just have a mounting tab for AC lines. There is also a BBC shroud available.

My sister and her family are in Hewitt. I'll tell her to keep an eye out for it when you have it back on the road!

Thanks for the info. Small world.

If the engine was a 6 cylinder in-line most would have just a metal "finger guard" curved top plate, no actual shroud. I have heard that 6 cylinder trucks with factory A/C did have a full shroud but have never seen one myself. Thinking that would be a rather scarce offering. No BBC 67-72 trucks were offered from the factory with 4WD, the 2WD BBC trucks would have a similar full shroud. Having a shroud does make a big difference in cooling. Just be sure the fan is positioned half way in and half way out of the shroud opening to obtain the best cooling effect possible.

My father in laws truck had a V-8 in it when we bought it. It had the finger guard only. I always a summed the PO had swapped it in and left the old 6 cover in it.

Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
