Default Re: Engine Block Problem (Mounting Studs Are Broken)

I had the very same problem If you can work the stud out you can redrill the same holes
with an "f" drill then tap for a 5/16-18 thread I used 4" cap screws and added an 1-3/4 alum.spacer but I needed room for the reed valve mod I was doing anyway. so far so good. dont drill any place else or you will have to repair case with jb as mentioned or replace cases or engine.
