Its the original to the car 318 radiator. They only offered 2 for the 1968-72. They had a smaller one for the slant 6, then this one for the 318-340 cars. Its a 2 row. It has a flex fan and it sits right at the shroud. when its hot and humid here, the temp creeps up when idling at a stop light. It will cool some after getting moving but still warm. I didnt figure it would be enough for the 440..

Here is mine for the 1968-72 v-8 A body
