Early A body S6 to V8 swap parts

It will be a 273 but not fully stock. Thinking about 360 heads with quad carb, was the recommendation from a local mopar enthusiast who did it already in the past with very good results. But for sure I will need some manifolds. As it is the early k frame I guess it will work with the stock setup. Sure I was thinking about converting brakes and axle but I guess I will do that at a later stage and start with stock. At least there are already powerbrakes retrofitted ;)
