    Asking my fellow buick guys their expertise on these products. This is for a 455
    the guy is asking $75 for the radiator and $125 for the fan shroud. That radiator looks a little rusted. What do you guys think?

    It appears to be a 72 radiator. What are the codes on the back of the tanks? Regardless it will take another 400+ bucks or so to get it back to where it needs to be.

    The shroud should have a number on the inside of the rim. It looks like it is missing some plastic.

    What is the intended use?

    I'm doing a 455 switch from a 350.
    What do you mean it will take another 400 bucks?:shock:

    It will likely need a need new core installed by someone skilled at not damaging copper tanks.

    It make have come from one, but I do not think it started out in one from the factory. It appears to be a post 71 radiator. In any case you need a 3 core original and not a 4 core.

    For your use get a new original like the one recommended by Csordas recently or someone else that has used one.

    I went on line to look at some 70 Riv radiators and they do have a filler neck like the one you posted. 70 A bodies did not . So it may be from a 70 Riv, but they are still not the parts that you need.

    If your looking for function get a aluminum rad and a 71-72 riv shroud should fit. I think I have an extra from a 72 GS 455 but they are usually around 150 and shipping also the fan blades are larger like 19 1/2 inches. for the rad to cool you need all these and a good fan clutch

    I had that exact radiator shroud on my 72 GS455, it fits and works but not the correct one for 71 with 455.

    Here is a photo of my same radiator shroud I had on my 72 GS455 when I got it and with the correct radiator shroud.

    I see not problem with it, it worked like it should.

    Ok, so it will work on my 71 skylark? also, this may sound dumb, but I can't use my 350 radiator for the 455?

    You'll have to drill a hole in the radiator top plate and maybe a U nut to use that 70 Riv shroud. But $125 is a little pricey for it. Especially if its broken. You can buy the correct 71/72 style for that kind of coin and I wouldn't expect it to be broken for that either

    There are no stupid questions, just smart alec answers!:laugh:

    No, the 350 shroud is a no go. You wouldn't even be able to make it fit

    Ohh yeah, I know the shroud wont work, but will the radiator work? or do I need a bigger one?

    A 455 makes more heat than a 350 all else being equal. Depending on the condition of your 350 radiator, it may or may not be marginal for use with a 455.

    Not sure how much room you have but I have a really nice 3" aluminum one with dual electric fans installed on it already. It was perfect for my hot 455 but was in a gbody so not too familiar with the abody requirements -- a little fab work possibly to mount and then your problems are solved -- I was only looking for $200 shipped. Would include virtually brand new lower rad hose too. Might give it some thought.

    Dimensions of setup are as follows: Out to out = 31", Top to bottom = 18.75", Rad thickness = 3" and fan setup takes up another 3.5" so 6.5" total thickness assembled.

    Have a two speed electric fan controller too that could be had for a few additional green backs.

    Be very careful when ordering an aluminum radiator. First, the lower outlet on that is 1 9/16". The Buick rads are 1 1/2" top and bottom. Second, I can't tell from that link how many rows of tubes that rad has. The stock brass/copper radiator has 3 rows of small tubes. The best aluminum radiators are NO MORE than 2 row. Aluminum rads use bigger tubes for better cooling. There is a ton of information on V8 about radiators. I suggest you do a search on V8 and read up, it has been discussed many times before.
