aftermarket aluminum rads

[mooseknuckles]

anyone using an aftermarket aluminum rad for their LS swap?....what kind?....size?..

[68Stepbed]

I just bought one from Dave's Truck Parts in NC. I paid $260 for it, and it looks and fits good. I'll post pics when I get them downloaded.

I would like to have one with the steam fitting already installed.

I bought one from Reliable radiators, Champion 3 core aluminum. dual fans ( 12" I think) and it was a direct fit. I should have had a bung drilled for the steam vent but I just went with the upper hose "splice" from Jagsthatrun.com

Could you use one thats comparable to the OEM size? I cant say I know the stock size off the top of my head...

[mooseknuckles]

I was just about to post pics of mine.

[nibs]

Do it anyways!

[mooseknuckles]

I did a quick measure on my stock rad and the core alone is 28"x18" with the tanks its around 34" wide...so the 31"x19" griffin should fit perfectly...the 45* on the lower rad hose inlet/outlet should help to clear the "Z" as well.....

here's mine from entropy... for ls swaps in our trucks....

[mooseknuckles]

nice unit!

I have a be-cool that was in my truck from back when it had the 355. Single fan, always on, and I'm ok with that.

[68GMCCustom]

I'm running a stock style 4 core with the Old Air Products dual electric fans that were made for our trucks. Low speed fan runs w/key on, high speed comes in if its needed and it all keeps my temp pretty much pegged at 180*

I apologize if this broke a forum rule. I looked through the rules and I didnt see anything regarding anything like this.

Here's what I used on two of my swaps:

Summit racing #380457. It is made by Northern (Made in China). I've ordered two and had to send one back because of poor quality control. Anyways, it has a built in 1/2-20 flare fittings for an automatic tranny as well as a 1/4" npt/npsm fitting that I used with a 1/4" barb for the steam vent line. Also, it has a 5/8" heater hose fitting that comes blocked off.
It fits perfectly within within the rad support using 4 core mounts. The intake on the driver side is tapered from approx 1 1/4" to 1 3/8"... the stock 5.3 hose slides onto this about half way up. The output is passenger side and also fits the stock 5.3. I believe it is 1 1/2". There is also a nipple at the neck for an overflow.
It looks pretty good but it is unpolished. I believe it is a 2 core. If you cross reference this rad it is listed for a '71 chevelle, gto and others.

Anyways, I've run it my blazer for the last couple of years. No issues yet. Although, I did recently send one back because it was warped straight out of the box, i.e. poor quality control.

It's an easy swap at $299. It is, however, made in China...
