I have a 1974 dodge dart 318/904 that i want to swap to a 440. I'm just wondering if someone could list some of the main changes i'm going to have to make to the car to make the big block work. I already have a bb727 trans. Right now it has 8 1/4 rear with higher gears (not exactly sure which size). original sb k frame. original oem suspension. It is front disk brakes if that makes a difference. it also has the AC firewall but i'm not sure if that makes a difference. Any info is appreciated.
