Randy, I have the stock mains with CRE's stud/girdle kit...we made 760hp on our first pull..the engine was installed in the car to break it in with a few runs and then it was re-tuned giving it another 100hp+...

that engine has been sitting and will be going into my Dodge..I started thinking about the street activity and trips to the track...I am going to order the BCR "bottom" kit that comes with the full "wall to wall" main caps and that 1/2" thick girdle...thats a well planned out bottom end for our stock blocks with 2 main bolts/studs..

no matter what you do, a stud/girdle to me, is a must...
