I am getting ready to start my 5.7/545rfe swap into my 73 satellite sebring (Roadrunner clone). I am picking the 09 Charger motor and trans up next week. My question is what radiator are you guys using? Should I get an oem style Charger radiator or use a universal style champion aluminum radiator? What fans and/or shrouds? Also are you guys using trans coolers with your 545's?
