Re: aluminum radiators...

I can't say much as I haven't used mine yet but I have a mishimoto aluminum radiator for a big block truck. It has a lifetime warranty, even if I'm in an accident I believe. If it breaks once I'm already ahead of everyone else buying another radiator. $320 or so I believe on summit.

Re: aluminum radiators...

Vehicle had a Griffin in it when purchased 4 years ago, running a 454 and it has worked flawlessly so far. If Champion has worked for you all this time and you're happy with them why change?

Re: aluminum radiators...

I'm running an OE-replacement Murray aluminum rad in my 82 C10 with a 350. It works great in hot Texas summers, cost around $130, and has a lifetime warranty from O'Reilly Auto Parts. They make 3 sizes for our trucks, and mine is the smallest.

Sounds like a good deal. However, all my daily drivers since 1999 have had aluminum radiators with plastic tanks, and I've never had a problem with any of them.

That's the exact same radiator I tried to buy from AutoZone about a month ago!
They do not sell this radiator in copper and brass as advertised on their website!Although they said they have it,they sent me the aluminum equivalent.
They did offer me my money back and apologized for the problem!

Re: aluminum radiators...

I'm running a Be Cool in my 79 k25. It cools the 427 tall deck in it great even with a 15,000 pound goose neck behide the truck. Even on 100 degree days. They are expensive though, I gave 700 for mine through Summit. But it was the only radiator I could find with tanks large enough for the larger inlet and outlet to be welded in.

We make bolt-in custom / conversion radiators for your application, right here in the USA using domestically sourced materials. Each radiator is built by hand and we use dual 1" thick cores, for a total core thickness of 2" (same overall thickness as a brass & copper 4-core).

We NEVER charge extra for engine swap port locations, steam ports or built-in transmission coolers.

We are a Gold Vendor and support this forum, and offer a forum-member discount ($25 off a radiator / $20 off fan & shroud package). Retail price is $470, and members of this forum get a discounted price of $450.

Hit me up with any questions or for a quote.

Re: aluminum radiators...

I'd like to see some pictures of the radiator, cooling fan(s) and shroud setup. I am trying to find a suitable aluminum unit in either a 2 or 3 row configuration.
Thanks

We have several brands we use depending on application. We have a black-label fan made for us for regular applications, and for higher power / towing / warmer climates, we use Spal or Derale fans.

For the fan and shroud, we use a flat style shroud to keep them compact.

Re: aluminum radiators...

I have a Spectra plastic/aluminum radiator from Autozone. Works fine in my 454 C20 in HotZona 100+ degree heat. Got it with 20% off and free delivery to my door for about $100. I think unless you have a high horsepower engine the regular Spectra is fine. I think it is a 3 row direct fit but the radiator is fairly thick in my estimation. My previous copper/brass radiators would not hold up in the heat. I am a plastic/aluminum fan now.

Re: aluminum radiators...

Here is my radiator from autorad the day i picked it up. Great quality thicker aluminum than most I have seen. This radiator was surprisingly heavy. So I know it is made right. Fully tig welded all the way around NO epoxy at all. With a custom fan and shroud with maridyne fans. rated at 800hp. It has two one inch cores.

Re: aluminum radiators...

I appreciate the responses to my questions,
regarding the overall thickness or depth of the radiator and fan assembly, I believe I saw a reference in one of the posts about the coils being about 1" thickness and that two together would be about the thickness of a full copper/brass radiator. Is that accurate? My issue is that I have only 5 inches clearance between the water pump pulley and my current radiator ( full 4-row heavy duty). Oh Yeah, and that is without cooling fans
I was hoping to find a unit radiator and fans to occupy roughly the same space with the cooling fans included.

BTW my truck is a 79 Scottsdale stepper with 502 RamJet and a Vintage Air accessory drive system.

Thank you again for your attention.

Tony

Re: aluminum radiators...

It sounds like you have a lot of money invested in your high horsepower setup, so I can see why you would want a high cooling capacity radiator. If you just want to keep the engine cool then I would think a stock Spectra radiator would get the job done. You could always swap it out for a better one if it did not work. I am not sure if that Ram Jet requires a minimum temperature to operate properly like modern engines.

Re: aluminum radiators...

hello and thank you for your response, I have had this engine since early 2000. I am not aware of any max/min. temperature requirement as yet. That might change as I get deeper into the fine tuning. Until recently the engine has operated on the crate included ecm.
This may all end up as overkill as I feel my way around the Holley HP efi. I am way over my head as I fit the new bits together and begin the tuning phase.

I will check with some of the vendors I see here and see if I can find something that fits.

Thank you again for your attention.

Tony
