1969 Camaro Fuel Tank options

[QUIKRNU]

I am building a 1969 camaro that will be mini tubbed. I want to build it using all factory or close to oem as possible. Its a ls7 with a cam swap makes about 625hp and 605tq I want to put Nos on it for another 175hp. I got the factory dry sump mounted between the rad and the factory spot for the battery. The oem tank with the fuel injection pump in tank wont work because of the mini tubbs. Will a factory corvette z-06 fit in and work or what other Ideas are out there?? Or is there anyone out there that builds a oem style tank for a mini tubbed car?? thanks
