Dingleberry or stone block
I’m a dingleberry hone guy myself but I had a 408 around 7-8 years ago that was on its 3rd rebuild. When I started honing it I couldn’t believe my eyes. This block was bad, real bad. I grabbed my stone hone and wore it out. I grabbed two new sets of stones and wore another set out and half way through another set. It was to close to race season to send it out to get it done right and even if I did honestly it needed bored. I finished it off with my dingleberry hone, washed it up, and put it together. I ran it for two years and my son ran it for 1.5 years. 9.74 in my car and 10.08 in my sons Duster.
