Turbo cold air ram intake

My turbo mag 318 duster constructed with a EQ roller headed, cammed, 62-1 turbonetics, 44lb /hr megasquirt controlled injector and CD ignition timed stock block 318& 904. I mounted the turbo near the passenger side of the radiator. I was thinking of constructing a box type attachment to the fender and radiator support. I would incorporate a large flat air filter and mount it forward on the radiator support . I would also use a turbo velocity stack. Thus, preventing hot under hood air while grabbing fresh air from the grill in a zero resistance atmosphere. Am I overthinking it??
