My Bull dog block looks decent, I chased the threads and checked the everything I could with the tools and measuring equipment that I have when I got it and did not find any major issues, now in saying that and knowing what I knew I did not go into this blind I understood the possibility of machining issues I am hard headed if I wanted something easy I would have bought a BB 69 Camaro and looked like the rest of the world !!! I will know more and report back here in a few weeks as this block will be headed to NC for machine work and assembly.
