I've got a Keith Craft 331 and it seems pretty good so far. I haven't really put enough miles on it to say its great yet. I do get alot of blow-by but I've been told that is normal on a blower application, by several people. My mechanic is
very impressed with it and that means something coming from him, he only works on mustangs and he has one running 8s.
On DSS, I heard alot of bad things about them years ago, haven't heard much one way or the other lately.
