What to do with my 360 magnum??

I would advise to keep the serpentine belt arrangement. it's smoother cleaner and is already there. don't cheap out on your fuel pump you want something that is reliable. both holley and Carter fuel pumps come to mind. as mentioned before you will need a 360 car oil pan and pick up tube. as far as your converter and flex plate be mindful that you need a neutral balance torque converter if you are going to use the balanced flex plate from the Magnum engine. without the power steering is the way you also have the option of using earlier Dakota manifolds, big ports good flow tight fit but wont hang too low. make.sure your brakes are up to the task , improved cooling.system and dont forget.to check.your t-bars make sure they're for.an 8 and not a 6
