1962 dodge lancer v8 swap. info needed

right and from what i understand there are weight sets to weld on. for the balancing.

as for the knob end. thats a new one to me. theres so many variables here lol. kinda overwhelming. lets say i end up with a good tranny good engine but that particular doesnt match. is that a part that can be swapped. or am i better off just finding one that matches in the first place and save myself the hassle. or maybe just go with a 318?

i also found a 360 with a 727 attached. but that wouldnt find underneath im assuming.
Not sure the 360 I have has a big notch out of it for balance will pos pic when I get home plus sell it if you need going with 4 speed like moving the leaver
