I would run a "nice" copper/brass radiator if I could find a supplier that handled a "USA made" radiator. I think I'm going to run an aluminum Griffin or BeCool brand in my '71 project truck. I was pretty disappointed in the 4-core I put in my blazer. It was "suppose" to be a Modine from
www.radiators.com,... BUT came in as a import look a like. Poor fit and finish. I installed it because I was in a jam. But that won't happen again.
