440 duster. Need engine build advice

The cast crank has been balanced internally I guess. It had been cut in the weights. I got the whole assembly for 800 bucks, so I'm not really out anything. It seems like it wad a budget build deal. The kids dad passed away and he was selling all the "car junk". I called Jim kilpatrick. He has some deal son cranks he had laying around ready to drop in.I will be taking everything to him for balancing. If the pistons are an issue then Diamond or Ross will be in order. I have the money to finish the build but I don't like cutting into my savings. So I will have a forged crank hopefully in 2 weeks time. Now I do have a set of 6 pack Ross and a set of ly just laying here. Should i maybe employ some of those options as well? This is seriously my first budget build. Otherwise it had been 440 source Stroker kits and indy heads. But those days are now long gone lol. I'm 25 and married....... However my wife is looking for a 67 to 69 barracuda for herself. Which she will build. But that's another subject. So now where do I go from here? Keep the bloc,k heads, and other bolt ons and just start over with crank, pistons, and rods? Thanks for the replies fellas
