If your looking to make serious power, this Main Support Girdle will allow you to do just that. This Main Support Girdle has been incorporated into our high horsepower big block engine builds. The purpose of this support system is to reduce torsional block flex by joining the three main caps, and the blocks saddles with the pan rail. It’s a proven method to completely eliminate block flex. Don’t be fooled by other inferior products that are priced less. They do not provide the same support as this girdle does and you run the risk of block breakage with inferior substitutes. Bar none, it is the only girdle proven to be reliable in preventing the Oldsmobile engine block from flexing and breaking.
