fan shroud

[gmclowsierra]

hi guys im looking for a fan shroud for my truck. I don't know the original size of the radiator but it now has the 21 inch radiator in it. ive called all the suppliers and they cant tell me what I need. they don't have listings with dimensions on them or even list them in their computer. ive tried lmc and brothers. the truck is a 78 with a small block 400. originally it was abig block truck. I have converted it to serp belt with the system off of a 97 chevy truck. it will have ac but not the stock setup. any help would be great. even better if someone has one and would like to part with it.

I have one of the large 2 piece deep fan shroud that came on the 305 & 350 engines in the 80's that might work for you. I can get the measurements for you if you want them. Looks like I'm about 2 hours away (due South).
Let me know.

Might I suggest an electric fan setup with it's own shroud. I put one in my 84 and I am not sorry many years later. I also changed my 91 Silverado daily driver to the same fan set up and gained a mile per gallon. The first pic is the 91 truck with the factory radiator and the second is the 84 truck with a Be Cool radiator.

Frank,
what brand electric fan setup and shroud do you have.
Thanks

There have been a slew of shrouds available, best bet is to go to the autowreckers and start looking for something with a similar setup to what you have. Rad height & small block, and you still may find you have something that isn't quite right. When I was looking for one it struck me just how many different variations there are for a truck that "never changed".
