It's a damn shame they dont offer modern rings even on the hypers. I have seen the metric rings pick up 18 HP compared to the 1/16 stuff

I'd imagine it is probably be quite a bit more compared to the 5/64 pack.
I am currently finishing up a stroker 340 with the kb416 .040 hypereutectic with the 5/64 ring pack. I am shocked at the torque necessary to turn it over by hand, (30ftlbs)
