mustang radiator with flathead?

I seen in so whats tec tips that a mustang radiator will fit in a 30 grill shell. Has anyone tryed the mustang radiator with a flathead? I'm thinking that it's going to be to small and i will have a over heating problem? I know you guys can help me here. Thanks Jerry

 

Same radiator I had in my comet and it wouldn’t keep the 289 or the 302 cool on 90 + degree days. Not even going down the road easy at 60 mph and that was a new 4 row.
I got a radiator catalog from NAPA and picked out something bigger.
I have seen shortened and turned up GM cross flows used in 32 shells.

 

Grimlok and I have discussed this, just add another inlet and outlet to a mustang radiator. If anyone has tried it, I'd like to know too.

 

A friend of mine has a rad from a mustang in his 30. Keeps it cool all day long. He had the extra outlets added onto the rad for the flathead.

 

That's what I used for my 8ba. I bought a new mustang 3 row last year for about $130 or so. I think it was from radiator.com I was in a hurry to get the rpu on the road so I thought I would give it a try. Does just fine. At first I had overheating issues but that was do to advance problems using duel 94's. Took care of that by redoing a chevy dist. and installing that. Of course like rodster said, you do have to add the extra inlet and outlet, but that's not much of a chore.

296, isn't the mustang rad the same one that FoMoCo put in the Comets?? Also in the Falcons.
So what your saying is that a rad. that FoMoCo paid engineers to design ,Then use in those cars for all those years, and that cooled millions of those cars sucessfully, but your not recommending it cause it wouldn't cool yours??
Don't you think there was maybe another reason for it overheating??
I bought a new 66 mustang, worked the shit out of the motor & never had it even go past 185o!!As a matter of fact I raise the rear of the hood(the thing to do in 1966) & took out the thermostat & the carburator got ICE on it in November!!
doesn't seem logical to me Mr. Spock!! Beam me outta here!!

All was trying to do was pass on my experience with the same radiator. In my case it was a bad experience that went on for over five years.
It started when I first got the car. In the summer it ran HOT(210) with a 3 row. So I got a new 4 row after checking thermostat – lower hose – bigger fan. With the 4 row it still ran border line hot(boil over after 20 mi drive) in the summer. So for five years I just lived with it, figuring it was just the old motor that probably had a little head crack or something.
A couple of months ago I put in a fresh rebuilt 302. Same thing, hotter(220 in 5 mi drive) than ever.
Having a new motor I was not content to live with it any more. So I found (1/3 bigger)a bigger radiator that would fit the space.
Now it will not go over 180 in 100 plus sitting in heavy traffic.
Do you still want to imply it was my imagination?
mustang-falcon-comet radiator only has a 16x17 core.
do flatheads run cooler than winsors?

 

I used the Mustang rad. in my RPU. It had a full hood and the motor compartment was tight. I ran an electric fan cause there was no room for a mechanical. It ran 185 all day long. I would cruise the fairgrounds in Columbus like I was in a golf cart. Never got over 185. We put one in Larry's truck with a mechanical fan and he has not had any problems either. I've had nothing but good luck with them. The last one I put in a 29 RPU. It cost $140. If I would have got a Walker or other rad. made for it it would have cost over $400.

Flatheads are known to be overheaters. Let us know how it works.

Thanks guys, I think i will give it a try. The cost for a new radiator for the flathead is $456.50. I bought a radiator for the tanks at a swap meet for $25. They want $450.to $500. to recore it. I'm going to talk to the guy at the radiator shop monday to see what he can do for me. Thanks again for all the help and i will let you know how i make out. Jerry

 

MBL's using one in his flathead powered roadster. We haven't hooked it up an ran it yet, but the radiator shop picked it up, cleaned it out, pressure tested it, added the extra outlets, painted it, and delivered it back to me at work for $65. That's a pretty good deal, for all that they did.

 

I'm running one in my coupe now.... well, I will.

I just got one of those three row ones from 1800radiators.com or radiator.com (I forgot which) for a hundred bucks. I took it to the local radiator shop and had them flip it upside down because the bottom is more narrow than the top, and had them put a couple extra water necks on it.

I've got a pretty good electric fan on it too... so it *should* stay cool.

 

Gee Johnny, I wonder where you got that idea from?

We've used these radiators in a few cars now, works well with a sbc, Y Block, and a nailhead. I'm curious to see how they work with a Flathead or Max Wedges Hemi.

Just be sure to run a 4 pound cap, the stock Mustang cap will overheat a flathead for sure.

 

How would you know what pound cap to use on a flathead Bob?? Has this occured to anyone lately?? FAG!!!

 

HaHa I've put several thousand miles on my shoebox, and it never overheated........... You can go how far? HaHaHa

Do you look at peoples porn when your putting it in their mailbox?
