I have a roller regrind from Ken 214/224 @50 with a 110 lsa and .512 lift.
Iit's pretty nice for building torque but sounds pretty mild.
If I were to, (and I may) get another cam it will be from them but with a little more duration though not as much as yours probably.
Ken hit this one on the nose for what I asked out of it.
Yours should be pretty nasty sounding and run good both.
Here's a link to a video of my exhaust with Flowmaster 40's and 2.5 dual exhaust. www.letsgocomputers.com/movies/idlesound.mov
