you could always use a remote booster off a slant six equipped Aussie car
i'd go up to fatter torsion bars
otherwise top idea
have a chat with Minty/terry he is sticking a 440 in his with a 8 3/4 out back
trans tunnel may need a bash or two for a 727. they had a special mallet at the factory when they did the 727 equipped police chargers
and the floor does for an 8 3/4
although ive been shouted down on here before i think the front of a valiant charger is ever so slightly wider than an A body. earlier aussie A body width K frames do not fit
headers? i'd look to Australia at least there is an outside chance they may have designed them based on fitment into an aussie Mopar i.e right hand drive with the steering box on the chassis
