Radiator Shroud Question

[70 GMC Trucker]

My 70 GMC originally had a straight 6 but was converted to 350 by a previous owner and a CU101 radiator was installed. Now with summer comming I would like to install a shroud rather than installing a expensive electric fan setup but can't find a shroud that fits. A shroud from LMC or Brothers is 28 1/4" wide where my radiator is 26 1/4" x 17 " x 2 1/2" ( 4 row ) Custom made ones are super big bucks so a factory shroud would be my first choice and if I have to go electric I've heard with a four row it's best to keep the blade and use a pusher electric in front. Any thoughts or ideas would be helpfull.

If I remember from your other post, the radiator is still a 6 cyl radiator. It looks like you have a flex fan on there from the pic, you could try to find a 6 cyl fan shroud and then get a smaller fan from the auto parts store.

you could put the factory shroud on and itll work even though its a couple inches smaller, or you could make one out of sheet metal

I've tried and tried but not able to locate a factory shroud for a rad for a six clyinder.

on all my 6 cyl trucks the shroud was the metal pc at the top of the radiator just like what's shown in the picture. I don't think there was a plastic shroud for the 6 cylinder.

use the factory 8cyl schroud it will mount up all you need to do is farricate a couple of 11/4 inch wide spacers on each side of it to seal off the airflo // its really an easy no frills fix that done right with some attention to detail wont even be noticable in the finished product

You were right..there is no other shroud for the I-6. And you mat be able to fabricate a new shroud if you want something cooler to use.

Fabricate? some brushed metal? know any tin knockers? Call Mcguyver

We sell a shroud thats 27" x 18" x 7" deep, but its for a 64-66

Hello 70' GMC,

I have the same rad shroud as you on my 70". I took it off a 67', thought it looked cool! I've yet to have a over heating problem. Are you having an over heating problem? If your not I wouldn't sweat it too much. I also have a new rad. These engine compartments are huge and air circulation is great. If your running a proper themostat and a good rad. I think over heating is not a big issue. I have a home made shroud on my 50' and this is something that you could do if you do not like the appearence of your present shroud.

I think yours looks good.

esll.

I haven't ever tried it, but it stands to reason that it might work. Try a 67-72 V/8 4X4 fan shroud. The 4X4s engines are located in the 6 cylinder possition from the factory, so that just might be the ticket. Otherwise its fab one up, buy an electric fan set up, or what I would do is to move the engine forward where it would have been located from the factory. WES
