Take a closer look and you'll notice that the carbs are A14T and the manifold I'd A12T. The carbs will not fit on the manifold. The English SU is 2 bolt like the Hitachi. The manifold and shield is half the battle. IMO the $250 starting bid is the value of the setup. No more. As you still need to get some carbs to suit.

What you could do is something truly unique for a road car is adapt two 40DCOE webers to it, only running one side of each carby like they did in the old PRC rally days. That would be cool.
