I have a 72 cuda im building a 440 for should be between 400 500horse im wondering if there are recommendations for a radiator ive been looking at be cool one guy there told me they have one that will work another guy told me that a radiator that is a direct fit will not cool a motor over 400hp I find this hard to believe being they came stock with nearly 400hp

 

You need a 3 row 26" radiator of some type with a fan shroud Check if you can bolt the stock style 26" radiator in from an AC equipped model..

 

which radiator support do you have?

 

He nailed it...

 

I have a large Be Cool unit that stretches from frame rail to frame rail in my Dart with a 440. It better cool it good cause it cost me 750 dollars.

 

Agree x3

I would also run the Mopar Performance Viscous Fan, that's what I run
