I am looking for an eliminator block that will sonic test as they advertise or atleast close to .200 at 4.700, I own one already but it sonic tested .164 on the thrust side at only 4.625 bore. I have sonic tested another elim. block and it was no better than the one i own. So i am looking for one that will go 4.700 and still be close to .200 thick as they advertise. Thanks .
