Gary, this might not be the answer you want, but HOW is your old radiator deteriorated? And, why would you consider changing from brass/copper to an aluminum, which transfers heat with much more resistance?

The only reason we use aluminum is for cost savings not efficiency. If you are looking for a serious cooler, recondition your brass radiator. It may only need lime and calcium removal to open each core. Phosphoric acid does that nicely, especially when heated. I gotta believe, when your car was new, you probably could have treked across the Mojave.

Mustang radiators (with aluminum core and plastic sides) are cheaper, if that's what you want. I have thrown two away so far. I still use the 'desert cooler' my '55 came with (on a 351W), and the original rad my '59 Galaxie came with (with a 292 Y-Block).

Most radiator shops will flow test your radiator for free. Bring it bare. - Dave
