Look, I know you are new here and only posted twice but in order for you to get an intelligent answer you must provide all the necessary information in an understandable format such as:

I have a 351W stroked to 392ci. I am running a standard water pump and radiator with a 180 deg thermostat. I will be driving it mostly on the street and not racing. Should I upgrade the radiator to one of those aluminum ones? Do I need a larger one than normal based on my engine?

You see by the example above how easy it is to understand and digest what you are trying to say? With this information we can give you the answer you are looking for. Now you try it.

And by the way, what is a "mauf at ac"??
