Hello all, i will be doing a 440/727 swap into my 318 68 Charger, I have a 8 3/4 with a 741 case. Would I have to change my drive shaft? Or can I reuse the stock one?

As for Motor mounts will I be able to use the same ones? Actually will I be even to use my stock k member? I am on a budget so I want spend the less if possible, I am not going for a complete resto. I am gong for something I can afford.
