Converting from 318 to 360

Thanks guys. You have been a great help. The rods are stock. As for the Oil pan I will be purchasing a Miloden pan. The stock looking one with or without windage tray? not sure? I already hate the fact that my headman headers drag on the crazy speed bumps. Not that Im flying past them. The block came with an oil pump. But I think I am going to purchase a high volume oil pump to be on the safe side. Since I have easy acces to it right now. It couldn't hurt. Also I couldn't find the oil pump drive shaft. Could I use the 318 oil pump drive shaft? Will this work? Last one I think. How can I tell if this long block is a LA or Magnum block? The casting numbers? The heads? Thanks again guys.
