To keep your newly purchased motor from melting down you will need a good cooling system. If you are staying in the stock horsepower range then you can pick up an OE replacement from a source like Original Parts Group. If you are upping the power of the motor then you will need to up the efficiency of the radiator and fans. An aftermarket aluminum radiator will typically provide better cooling properties over stock copper core radiators because Aluminum dissipates heat more efficiently.
On the bigger end of the cool meter is the combination radiator and core support cooling system by AutoRad. This is built to bolt right in to your Camaro, Chevelle, Nova, or Tri-Five shoe box and provide 10-percent more surface area than a stock big-block radiator. No matter what radiator fits your budget make sure to use a high quality belt driven or electric fan paired with a shroud.
