I'm in the process of doing up an L67motor and I want to stroke it. Is there a cam that would be beneficial or suit the stroker kit?

Unless you changed the supercharger to one that could handle the stroked engine then it is not recommended. However, you could just install one of our cam packages. The COMP cam package will yield substantial gains;
