There is a Canadian guy that runs two red Plymouths in Stock and SS with MW engines. He calls it Red Door Racing. I sort of forget his name at the moment. He's on FaceBooger. The 518-M castings are hard to find, and you want the later ones from what I've read on them. Welding up aluminum heads is easier to modify.
