Well, the 351M is kinda tired, not running the best oil pressure. From what I read thats pretty typical of these when they get old. A kid I work with has a 400 I am buying from him this fall if it doesnt go anywhere. His motor only has 30k miles. I just need to swap oil pans since it came out of a 77 2wd. I will throw some pics up tomorrow night of the new beast.
