I get radiators recored on a regular basis lately, Chris, and I always opt for the high efficiency cores that have maximum fin density just because I also have to deal with Los Angeles temperatures while I have my a/c on, and want my coolant to stay below 210F under the worst traffic conditions on our freeways where there are plenty of just stop and go periods for many miles.
Dave's bill above represents a high efficiency core for a 22" radiator for a non-a/c car and I have found that lately I am approaching $600 for a 26" wide a/c radiator with 3 rows of tubes (my radiator guy believes that going to 4 row cores is not a plus unless your car overheats on freeway cruising which is never the case for me at least and just adds more mass to cool down in traffic that would actually be a minus). Actually the cost of the recore for me hasn't changed all that much from say 8 - 10 years ago since I can't recall ever paying less than $500 for any high efficiency recore job, which mimics what Dave is also saying.
By recoring your own radiator you can also maintain your original toptank in most cases, which is a requirement for any radiator I have redone for one of my cars.
I personally would want nothing to do with an aftermarket radiator such as Spectra Premium for example as listed above - out here in the southwest they are just worthless and have lousy fin density which is vital to cooling efficiency. Overheating will be guaranteed. You get what you pay for especially in the case of radiators.
Chrysler never designed in enough cooling efficiency for hot weather such as ours when new - I saw the data at the Chrysler Chelsea proving gounds back in 1970 and it was poor and they knew it but saving money was king so they stretched the margins. That is why Imperials at least got the 28" radiators even though they are much the same cars, especially in traffic conditions (radiator width is important for low speed cooling - more the better and radiator depth - no. of tubes is important for higher speed cruising).
My advice is pay the money and you will not regret it.
The only reason to go to Glen Ray is to get a really competent job done but the surcharge is hardly worth it given the radiator guy I currently have. I have one of the Glen Ray versions in one of my 71 300s (photo below). It looks great but cools the same.
