Looking to trade my 750 Quick Fuel carb for something bigger plus cash on my side

I have a perfect 750 Quick fuel with roughly 200 miles on it that I would like to trade with cash for a larger carb for my new motor. Going with a 512 stroker so let me know what you have and how much you would want me to add to make it work. I will also have a entire 383 with 906 heads for sale if anyone is interested let me know.
