To bring this back on topic, at one time you could buy a adapter intake to run 351C intakes on FE blocks, and spacers are available to run BOSS 302 intakes on 351C's
so all you need is to buy a complete Cross Boss Intake and Carb ($2000) and then find one of those PSE Intakes For the FE (probally 300-500 on the bay)and then a set of spacers from Price Motorsports ($200?)
