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

My 1990 4x4 350 Suburban with a/c, has what is obviously a non stock radiator. The shroud is pretty much jury rigged. I believe it is the original shroud. The radiator is 19 x 28.25 x 2.5 which according to lmc is a 4 row for the 454 from various years from 73 to 87 depending on options. The 2 piece shroud in the vehicle now, has clearly been cut in order to get it close to mounting right. What kind of shroud do I need to use to get everything to fit, and work correctly?

If your going to keep the radiator I would get a shroud for a 1990 454 suburban or better yet just install electric fans .

Definitely keeping the radiator. Just had it completely renewed, so it's basically brand new. Electric fans are something I've considered. Just wanted to confirm that using a 90 454 shroud would actually work.

I would highly recommend a dual fan set up. It will help out your engine a whole lot. But the 454 shroud will work and it should fit over your bigger rad.

Probably going to do the ls1 fans. Just don't have the spare change right now to do it.

So I now have a 454 shroud, but I don't have the panel that goes between the radiator brackets to completely seal the shroud to the rad. Anyone have a source and/or part numbers for this?

LMC should have a diagram.
