Overwhelmed by radiator choices: 37 chevy

I guess this is the place to post this.

I'm a bit overwhelmed by the choices available for radiators. I have a 5.3 LS motor going into a 1937 Chevrolet. So far it seems Harrison or Walker would be the best choice.

It's a stock motor and I'm looking for something that would easily bolt into place without much fuss or modification.

Thanks,
Brandon

Take a look at PRC. Lots of discussion related to traditional materials vs. aluminum. If you like aluminum, PRC does a really nice job. Great looking welding.

Thanks for the tip, I'll check it out.

I don't know very much about the subject as far as Aluminum or Copper. It seems like one of those topics that people might die defending their side but I have no idea either way.

I just want something I can put in easily and will last for 40 more years.

I don't know about the 40 yr part but PRC is a very nice alum. rad. and a lot less money than a Walker Z. Here's some pics of my '32 Ford chassis with a PRC.....the tig welding is fantastic.

By the way, I have a good friend that is a dealer for PRC and can get you a helluva deal on one. If you're interested send me a PM and I'll give you his contact info....Dave

I have a Walker in my 32 roadster. It is over 25 years old and NO ISSUES yet. I have a Walker in my 32 3W also. I do believe that WALKER is the very best ... BUT ... it is also the most expensive.

_________________________________________


I myself have never bought a aluminum radiator. I always go with the brass/copper ones. I have a few friends who tried the aluminum ones and after a few years ... they went and bought a new brass/copper because of the leaks and problems with the aluminum ones.

The brass/copper VS aluminum debate has been going on for a long time ( as long as the aluminum ones have been on the market ). Most folks have their own experiences.
Most are set on their opinions.
A brass/copper one also LOOKS correct ( to me ) in a older vehicle.

You can go here to see my 32's ...

I plan on using a flex-a-lite , but its not a direct bolt in, however they are about the easiest to make brackets for because of the way they are made

they also have custom made choices
also they are a local company

I think the big thing with alum rads (if thats what you choose) is get one that is welded not glued


let us know what you choose and how it works out

Thanks guys for the input. I definitely would not want something that is glued. That definitely seems like a bad idea. I'm going to look into the ones mentioned here.

Thanks,
Brandon

I bought a superior aluminum radiator for my 38 coupe on ebay. Price was very good, quality was very good and it cools very well. Having said that though, they advertise it as a direct fit for 37 38 chevrolets. NOT! they welded on the mounting brackets at the wrong angles and the wrong position. I had to do a days worth of fabrication to make it fit. When I called them about the issues they said that I was the first complaint they had received. Ya right. I just checked and they are still selling them on ebay though.

As Spacy found out, the old "you get what you pay for" is very real. To the OP, the Griffin alum. radiators were not actually "glued" together. You would have to read their Q&A section of the website to get the reason why they used epoxy in the build. They did have a number of failures with them though and you want a radiator...alum. or brass/copper thats all welded.

And to Deuce, we have discussed this alum, vs. brass/copper before and I truly regard your knowledge and expertice at a very high level....and again to each his own. I know guys that have been running alum. rad. for years with no problems.......and I must say I got a chuckle out of your remark about "a brass/copper one also looks correct" from a guy that has a ZZ430 and zips riser along with some chrome goodies in the same engine bay as the "correct" radiator. No biggie, just struck me kind of funny.

Well, I bit the big one and ordered a Walker. It has the built in trans cooler and air conditioning condenser. Guess I better start picking up cans to recycle to make some extra money.

Yes ... but when you look at the front of the Deuce ... the radiator looks " correct " to me. Not shiny, silver or aluminum.

I also do not like the welded up tanks ...



The GREAT thing about this sport/hobby is that we can do and modify our vehicles like WE WANT ... unlike the restoration guys who are limited to what is right or wrong.

I have a Walker in my 36 Coupe and been trouble free with superb cooling for 13 years. I have a Griffin in my 36 Pickup, only because Walker does not make a radiator for the 35-37 pickups and it has been trouble free for 12 years. I still prefer the Walker and by the way, they were almost identical in cost with the same features (condenser, tranny cooler, max capacity and cooling fins and good to 20PSI). The Walker is cooling a warmed over 327 and the Griffin is cooling a hot 383. I am using a 2700CFM electric on the Walker and a relatively flat flex fan on the Walker.

I have a buddy that has a '37 chevy. He bought a aluminum radiator from a place in Evansville IN. I'll have to ask him the name of the company. Anyway, he had a problem of it leaking in the corners where it was welded. We tried to have it re welded, but it came back. He took it back to the company, they said it wasn't able to be fixed. They said what happened was geothermal expansion. Basically, hot water in the engine hitting cool water in the radiator caused the corners to separate. They gave him a new one at what it cost the company to make it, then told him how to keep it from happening again. They said to drill (3) 1/8"dia. holes into the thermostat. That allows the radiator to warm gradually instead of all at once. Just figured I would share that tid bit of info. I'll post the name of the company as soon as I find out.
