i am looking into changing my block and going forged.I was thinking about looking for a used one online. I wanted to know what are my options as for as motors from other cars that would work.I know some explorer blocks and lincoln blocks would work but do any of them come with the forged crankshaft and rods, and what about the mach one motors , do they come all forged or just the crankshaft.Or am i wasting my time and should just look for 03/04 cobra block or a MMR block.I dont mind taking the engine apart and putting back together but i figured it was easier changing the block and then doing heads and cams later on.Thanks for any help
