65 Valiant swap 273 to a 360

AND... Did you know???
Two more items here. It is easy peasy to swap an A-bdy 727 tail housing and output shaft onto a B/C/E/truck/van 727.
Yes, you MAY have to massage to floor and/or firewall pinch weld a bit to make it fit, but it will. Imperial Services makes, or at least did make, a cable kit to adapt modern lever shift 904/727's to the earlier pushbutton, and I believe console shift, cable controls. Not inexpensive...

NOW, the pièce de ré·sis·tance... I'm not positively sure about the '65 A-bdy 904, but it was still cable shift, SO, I think it does apply here... Definitely up through '64, you could push / pull start a Mopar with a 904 trans, because the pump is in the rear of the trans, not on the front like newer versions. In other words, if you were turning the wheels, then you were turning the pump. If it is in gear, then with enough speed (pump pressure), it will spin the crank like popping the clutch on a manual trans car. I have seen it done, and if you search YouTube, there are a couple of demos / examples shown there.
