440 swap

i was gonna do a swap in my 72 duster But everyone says it’s a pain to work on

Big block mopars do have some major advantages to the small block on ease of working on. 1) distributor in the front 2) oil pump can be changed without removing the pan 3) no coolant passages in the intake 4) oil pan is completely flat 5) oil filter in front. Only real minus in my eyes is spark plug access is a tough.
