this should be in the 440 forum just so you know. you need to get low comp heads. you can get 02 arctic sno pro ones or speedwerx makes kit. you also need to get your ecu reformatted(i beleive thats the word). for the cooling i would deffinatly put in a rear heat exchanger. you can go with the under the tunnel u cooler or the side tunnel coolers. look in the 440 forum theres a whole 23 long page thread about this.
