Yes I believe you are correct. I have a set of 317's but I'm going to opt for the brand new GM castings that PRC uses. In my case, I know the original motor was overheated- so after spending ~$3k in a rotating assembly and ~$1k in machine work, I'd rather have the peace of mind of brand new GM castings
