But it cant hurt to look around for someone who bought one and then abandoned the build or something and you might get one cheaper.
Also please keep in mind that while a girdle will help a healthy block stay healthy it wont help one that has defects already. Horsepower has nothing to do with block longevity. Well it does, but torque is more relevant. Keep this in mind. Also a good INTERNAL balance will do wonders for high horsepower builds.
