Biuld worth-stock/clone vs protouring $$

What would be worth more done on a `71 Duster originally /6, stock looking clone/tribute style or modern street machine/pro touring type build? I`m currently collecting parts for the build and since it will be for sale when it`s done to make some money need to know what direction I should go as I really haven`t decided yet. Keep in mind it will be a very low budget as in around $3000 total so a lot of swap meet used parts will be needed. I do all the work myself so it can be done, I did my last project `69 notchback Barracuda for around $2800, had fun driving it for a while and sold it for $6000. Power will be a smallblock as that is what I have parts for and will be auto trans. Cra is already minitubbed so wide meats on the back will be easy. What are your thoughts and ideas?
