this is true , I thnink you might want to start lokking that way cause that 318 has seen its last days with that piston thing. The only trouble is the mounts and the exhauset and you can get those. Buy the 440 and get started. It will be better tahn throwing you money into that 318 and watching it go down the crapper when you fire it up and the pistons go.
