I have a 1969 cutlass s convertable with a 350 V8 with AC and automatic transmission. What size radiator came from factory. Trying to figure out if I need a 4 core or something smaller since I don't have a big block.

 

I am thinking of going with a 3 core aluminum radiator any opinion's?

 

Sorry nobody replied to your initial post. Your car could have had a 2, 3 or 4 row radiator. Since you have AC it was probably a 3 row, but may have been a 4 row. I know several members here have gone with aftermarket aluminum radiators. I would think it depends on what part of the country/world you live in. In Canada or Northern states you might be fine with a smaller radiator. But if your in the South or even somewhere with lots of 90's and stop & go traffic you may want a larger one.

Do you have the top plate that holds the radiator down and attaches to the top of the core support? We can probably help you identify what it had from the factory by that.

I wouldn't go with anything smaller than a 3 row with A/C if your thinking about a replacement, I would suspect you have a 3 row in it at the moment. Also as John explained it would also depend on the summer temps where you live.
