Customer project car. 35 2 door. Trying to determine if the radiator is actually a 35 or, not. (see pic)
The engine is a later 24 stud with center hose connections. I am trying to determine what hoses to get.

Looks like one of the two '35 versions, but need to see the top and one side to be 100% sure.
 
Top looks right, but it appears that it is missing the bracket on the side of the radiator for where the forward hood side panel latches. Maybe it's just the photo.
 
Something along these lines will work for radiator to center head outlet connections. This looks to be custom bent up. Several suppliers have tubing that is better in appearance that work.

Bracket for hood latch is there. Just not in photo. Now there is talk of going to a modern aluminum radiator. We shall see.
 
Had my 35 radiator record. supposed to be more efficient than the original. I have heard aluminum is not as efficient as brass
 
No, aluminum radiators cool much better than brass/copper.
Reason: aluminum radiators have no lead solder/flux joints. Lead is a terrible metal for giving up heat. Aluminum radiators are 100% furnaced brazed and have no solder joints. Much more efficient for their size.

But brass is original for our cars and are preferred for that reason, not because aluminum ones don't cool as well.
 
Here are some photos of a small tank 35 radiator to compare with yours. Also a closeup of a hood latch bracket. There are formed rubber hoses that should make the transition from center outlet heads to radiator necks. A flexible hose will also do the trick.

Except for the aluminum ones that are epoxied together.

yada yada yada...


However factor in that copper/brass/bronze (or stainless steel in some applications) can have a much thinner material for tubes and fins, and the efficiency increases as the material gets thinner and more rows of fins can be used... Bottom line (as near as I can tell) is that well constructed and designed radiators are approximately the same efficiency. The next issue is load bearing structure. Radiators of the 1930's carried the weight of the hood and grille. An all aluminum radiator is not going to handle the structural stress as well as brass (with steel framing) did. A significant part of the cost of a new radiator is material. Because an aluminum radiator weighs half of a brass one, and the brass costs five times as much the brass ones are much more expensive. Weight saving and cost saving, not pure cooling performance, are why aluminum radiators are popular now for new applications.
 
Pros and cons on both types but you can't make an assumption that just because it has an aluminum core that it won't cool as well.
 
The research I have done on this topic say that brass and aluminum radiators are about the same in cooling ability.
 
I just ordered a Champion aluminum 3 core radiator for my 41, it never ran hot with the copper core, but it's shot. I have an aluminum rad. in my 55, I will tell you that it will disapate heat faster than a copper one. Don't lean over the top tank on the aluminum one or you will be branded.

Don't forget a rattle can of black radiator paint.:cool:
