I tried to find this before bothering anyone, but no luck: I have John's Blue Thunder intake on my mild 312, but I am very interested in how it compares to his new hi-rise intake with that cool logo on the top.  Is there a thread somewhere that I missed that gets into the subject of comparing the performance differences between the old Blue Thunder and the new intake (don't know what it's being called at this point) intake?  Also, are the Blue Thunder intakes still being produced?  Many thanks, Ron
