Radiator Shroud

Has anyone ever used one of those Universal radiator shrouds for their car? If so, how did it work? I am thinking about getting one for my 72 Chevelle with a 454. Currently I don't have a shroud at all, so I definitely need one. I like the look of the universal, but don't want to get it if it's not going to help cooling.

Pay attention to the "fan to shroud" interface. The fan, optimally, needs to set about half of the blade width into the shroud opening and that opening shold be about an inch or so bigger then the fan (per side). As long as you can get to this relationship the fan will work efficiently and the shroud is able to do it's job. Now, doing a better job then no shroud depends on the set-up. A badly designed shroud can be worse then no shroud at all....

Are you guys referring to the "box-type" or the "strip of sheet metal" fan/radiator shrouds?

I'm not trying to be picky! It's just that I have the same question (I think) that JamesRS is asking.

I'm finishing the buildup of a SBC 405 (400 + .020) and am planing on running it behind a "Be Cool" 18" x 26" Aluminum radiator with a 16" puller electric fan.

Trying to decide on a shroud configuration and whether to build, buy or modify.

Thanx!

That is the type that I was referring to as "strip of sheet metal" - nothing derogatory intended.

I will stay tuned for (hopefully) more responses and recommendations re your original question.
