   The aluminum radiators that appeal to performance enthusiasts have   
   aluminum tanks too. The weight savings over a 1979 factory radiator (brass   
   core and tanks) v an Aluminum radiator raised the front of my 79 Malbu by   
   nearly an inch...not to mention that the aluminum radiator dissapates heat   
   faster. I also kept the factory (plastic) shroud, but replaced the heavy   
   clutch fan with an aluminum flex fan, which pulls more air at street   
   speeds, but flattens out at high RPM racing speeds.
