Great post, Dave, with good info on rad make-up. I just re-cored my rad and, as is sometimes my misgiving, thought the 'more is better' theory should apply to the 2-row, 3-row core material. After a quick tutorial by the rad specialist, he soon convinced me that what you have stated re number of tubes and quality of construction has more to do with maximum cooling than just 'stacking up the rows'. Easy enough mistake to make though, I suppose. Same goes up here in Canada with rad shops... used to be many - now they're few and far between. Have to say though that with the re-cored rad and new, not rebuilt water pump and a freshly flushed block, the car sure 'holds her cool' now and I'm not sure enough can be said about getting rid of old radiator tubes. The mineral build-up in the already-small tubes can be a working engine's worst enemy. Just for curiosity and cross-border comparison's sake, my rad bill was $800 CDN or about $595 USD Chris.
