Awesome wagon! Great colour combination too. Those pics have me drooling. The tail lights on those '63s were pretty neat. They look cool at night with their inset, segmented trim. I bet she sounds mean.
VERY cool car! am i seeing cast iron manifolds or headers? looks like some type of rare cast manifold?
Maybe I have seen too many Max wedge 426s with the crossflow two 4 bbl set up, but that engine looks like a 383 to me. The upper radiator hose run to the radiator is definetly the way the 383s were run.
Those are Max Wedge-style manifolds. The OP's wagon is somewhat of a tribute car, but those were the manifolds that came from the factory on Max Wedge cars back in the day.
