I am looking to upgrade to a direct fit aluminum rad and would like to know what has worked for others.....I have a 66 coupe with a 289 4 speed. Car runs really hot in the hot summer days, over 220 when sitting at a light. I am rebuilding the motor and beefing it up and would like to upgrade the rad so I don't damage the motor. I am looking for the best cooling I can get for a reasonable price. See lots on ebay but would like to get one that is a known supplier that guys have had luck with. thanks alot
