Doing this 440 big block swap, i currently have an a body regular V8 size aluminum radiator. Will i need to upgrade to a larger one like what woulda came in a charger? Current setup has absolutely no issues cooling the 360, in fact it kinda runs TOO cool, but a 440 is a lot more motor
 
I see 10 pages of text coming, but you'll be just fine. Bottom hose will need some RTV and a tight clamp though, as the spigot is one size smaller than a big block radiator.

That answers that for me. If its different ill just upgrade. I didnthe dance of wrong sized outlet 9 years ago on a 71 dart. Never again
 

It might work and it might not. Depends on how good of shape the parts are in, and how good of a mechanic you are. I'd say the smaller radiator is marginal for a big block, but if you have a good shroud on there and a good fan then it might work for a car that isn't driven too hard or too far in hot weather.
I used a C body radiator in my Duster since I was going to use a 600 hp engine. If you use a stock 440 then a smaller radiator will work.

Try it & see. While the 440 has more cubes, the engine will have less load & need less rpm than a smaller engine to move the car.
 
Really depends on the engine. Stock or close to it a 22" will keep it cool, stroked, hot cam, etc you'll need a bigger rad. TONS and TONS of info on this forum about this.
