ok guys we are going for a radiator now ,,,

A stock replacement or a aluminum one ?

We are not looking for a #maching , one later if the car get that kind of resto.

I'm thinking a stock w/extra cooling ..and a solid mounted fan or HD flex fan. I have been told by more than one SB owner that they run hot do to the lack of air flow when going less that 1,000 MPH....

all your feed back would be great ...

Stock.

I have an aluminum radiator, but a stock one has the advantage of easy mounting and it's easier to find a shroud for it. Shrouds make a huge difference in cooling.

If I were you I'd look at a stock type radiator with a shroud, and a clutch fan.

I was in your shoes about a year ago. My stock radiator (a parts store replacement from the 90's with no #s) just wasn't flowing. Local radiator shop closed up, so I really couldn't decide what to do. After freshening up the engine last year and finally going with an aftermarket temp gauge, I found that I couldn't even go five miles without running hot. Repops are big, big bucks. I wanted aluminum, but didn't want some generic Jegs type radiator. In the end, I wound up buying a new aluminum radiator from Wizard. I'm not crazy about the looks of the top tank, but it DOES accept the stock fan shroud perfectly. I run a cheap light weight plastic fan from Jeg's and the car will run at 160-170 all day long on the highway while buzzing along with 4.10s. I've idled in traffic and haven't seen it climb past 195 and as soon as I start moving it drops back down. I'm happy with it. Picked it up at Carlisle for $500.

kool...

The conventional top tank style aluminum from Mancini and others would be a good choice. They are high capacity and, when painted black, don't look out of place. I'm running a 26" version with the MP clutch fan in a Challenger and it works great.

I've heard some of the stock replacements are thin cored and low capacity so be careful if you go that route.

I have a Ron Davis radiator in my Challenger with a 505" stroker and it never goes above 180. They have direct fit replacements or can custom build anything you need. I was able to use the stock fan shroud and it bolted right in.
Made in the USA too.

GlenRay radiators can build one with no part#s that will cool a wing car with no problem and still have all the correct mounting points for the car and the shroud for around $600. Bob has a good number of his rads. in wing cars and they do not have a prob. cooling even just driving around town!

Griffin makes a 26 inch Aluminum bolt in that can be painted black and looks close enough to original. Cost around $500 at Summit. You can mount a shroud to it also.

Check out the posts on the Champion radiators. They are cheap and most people seem to like them. I will probably go with one when I get that far.

Options to look at.

1. price
Stock or direct fit aluminum - $$$
generic aluminum - cheap

2. fabricates skills
very good - aluminum
ehh not so much - stock

3. electric fan or pulley fan with stock shroud
pulley fan - stock
electric - aluminum

I tend to thinks the new aluminum radiators cool and have better flow than old, mainly due to width of actual cross tubes and airflow around them so I perfer the aluminum.
finally as said they 500 will buy a direct fit aluminum with correct mounts radiator.

I used a brass triple flow 22" radiator when I converted my '69 roadrunner to a 526 hemi. It runs pretty cool and never overheats even without a shroud. The radiator looks pretty much stock too which is what I was looking for.

26" Stock. Ma knew. Cool. All day long.

Hi Dennis

I was hoping at least one SB owner would post in here ,,

My big deal is that the SB radiators are not open to the are like everyone else ,, The air has to find its way threw the some what small opening in the lower side of the nose ..

But to combat the lack air flow im going more to the Aluminum.. is would dissipate the heat faster/better and this car will see around town and stoplight most of the time ,,,

I sure would like to put some miles on your car for ya. I would realy have a hard time giving it back to you though. It's been many years since I've seen a bird that was actualy just driving around. They're all in hiding now days. That saddens me.

Summit aluminum radiator 160$

Small block use a ma Mopar rad. I use a large one from a Dodge van in my 73 This past weekend it was 93, with hummidity near 70% drove it around with a 195 stat and never went over 200 race it that way too with gears and short tire it may hit 200 cruising at 3800 at 65-70. A good recore with more fins in between the tubes makes for a better rad. Brass/copper.Small block 360
