I agree. I got a 4 core Champion a few weeks back for the 69 Dart. It was only a 22" core support so I stayed with the 22" and added more cores. This was a direct fit to the radiator support with no modifications required.

Yes, definitely use a shroud. Use a clutch drive if aren't already. You might also look into getting a 3rd row in your radiator if possible. tanks look big enough. it's not as good as having more width, but it does help. and I agree on not cutting, don't think you have to. be creative, and it's a good feeling when you don't have to cut

Stu I just put this in a little over a week ago. I haven't made it to the shroud stage yet. I may see how it does without one and if its not needed I may not run one.

classic problem. I think a shroud would help that a lot.. but obviously so would more capacity. how many rows in the radiator - 2?
How crafty are you? There are many options. Like was already mentioned, you could do a wider aluminum unit, offset it like shown above (which is a very elegant solution). I'd couple it with a shroud.
you could get a third row added to your stock radiator if can fit another row, and if you don't already have it. Again, couple with shroud.
You might also test the clutch drive - I've seen them bad right out of the box, especially if they are old were stored improperly (they can leak the fluid)
Are you running a thermostat (you should be)? What temp?
You could always buy an aux electric fan and mount it in front of the current setup. a simple switch could turn it on for you (or you could make it automatic with enough ingenuity). that'd be a huge help at idle when there is minimum airflow across the fins
don't forget - in a bind, roll down the windows and blast the heater. that can save the engine and bring the temps down. I've been there.. sure aint fun in the summer.
My father once routed a spare heater core in the front of his 64 413 New Yorker, which was prone to overheating. he plumbed it in via the heater hoses, and he said it never overheated again. sometimes you just need a bit more capacity. that's not very pretty though...
Which fan are you using? You want the 7 blade one

I am running a 180 temp thermostat, yes i do have a shroud, the clutch fan is a 7 blade type.
The radiator is the stock type but maybe having it recored to three rows is the good answer to this problem?

I tend to type too much. these guys put it better - need more air across the radiator at slow speed. so - 7 blade fan (you got), shroud (you got), and as mentioned several times, an electric pusher fan at the front. modern cars do this, and it works out very well
Do you care if it will spoil the retro look? Otherwise, you'll need to do recore, or aftermarket radiator with a bit of fab (more money).
if you rig up an electric pusher fan, it will always still work with an aftermarket radiator if you need even more capacity, so it's not like it'd be a waste if it wasn't enough (but it probably would be).

but the cheapest approach would be to add a fan.
That was my first idea as it seemed the easist, but i have asked all kinds of people who have added electric fans to their cooling systems and they said the only way to make it work correctly is go to a puller fan behind the radiator and not in front. There is no room for a puller unless it get rid of the clutch fan altogether unfortunitly.

They gave you bad advice. with dual pushers on an aluminum radiator, you wouldn't even need the mechanical fan (although it's nice to keep it there - big iron engines make a lot of heat and it helps to have something to blow it out of the engine bay). Think about it. going down the road on the highway, the wind acts as a giant pusher fan. you don't need the mechanical fan, then. all that stuff is there for when the car isn't moving or is moving slowly. the single auxillary pusher fan will be a big help
