will Edelbrock LD4B intake bolt on to a stock 1964 318 poly

The thing is, every single dual plane 4 barrel manifold I find that is advertised as for the 318 mopar small block will not fit on the 318 that came in my 1964 fury. Is this the difference that mine is a 318 Poly and these other aftermarket parts are made for the 318 LA?

Anything offered aftermarket today will not fit the Poly 318, and it will be for the LA 318. As others have stated, you will have to source either a factory single or dual quad intake, an old Weiand intake etc. There is a new company that is making manifolds, but they are pricey. I loved the Poly that I had in a 65 Fury, it was torquey and gave decent fuel mileage as well. Good luck on your hunt!
