By the way, in my 1957
Pontiac wagon (my tow vehicle) a few years ago I decided I'd switch to an aluminum radiator. With some serious mods to the rad support I was able to move up to a 31" wide radiator, from the original 25" width unit. A friend with a 1955
Bel Air did the same. I've had no problems and no heat issues since, and I also bought a Mr. Gasket thermostat which are far superior to the Standt and others I've seen. The fellow with the 1955
is now on his third replacement (number 4). We do not know why, nor does the radiator manufacturer. They've been outstanding at warranty and everyone recognizes that there's a different problem than just the radiator - whether it's mounting or what. But he never had an issue with his old copper radiator and it's now in getting recored and is going back in the car. We've learned that aluminum radiators do not cool any better than copper radiators, what they are is a bunch lighter and look pretty. I am also considering having my original tanks removed and the original recored and stick it back in. I can't speak to the quality of any one type of radiator but what I've found is an old timer radiator shop who ask a lot of questions first about how I'm using that particular vehicle, engine size and whether it's stock or not, what I'm towing, and then he makes a suggestion. So far everytime he's fixed something for us it's been done right and never a problem. A buddy who's built a radical custom out of a 1953
Ford had him build a radiator and had thought he'd be suggesting an aluminum radiator but the one he got was copper and it works great, even in a car with tight engine bay and poor air circulation. I'd suggest you check around your area for a radiator shop with people at least as old as you, with hands that show they actually do the work on the cars, and ask them for advice.
