if you are going to use a girdle, the only one worth buying is the bcr piece in my opinion.

It is more machine work, but when its all said and done, you look at it and say with out question that it will help.

I run one on my motor labratt....remember, stock block and 1300hp

It also comes with the aluminum main caps, the girdle ties the pan rail to the main caps (all of them) and is a top notch piece.

I actually tried to purchase the BCR product line from Greg, I was such a firm believer in it.

Becareful of the type that use washers and spacers to make up the difference between the mains and the pan rail as those really dont do what you are looking to accomplish
