      Part No. SP31-G4-B


      The blocks are 100% NEW GM Gen IV blocks. They can be used for a Gen III application, but you will need to purchase a conversion package from ATK to make this work. Please call for details. This New stroker short block is built for engines that will be used for Boost or Nitrous applications. With these builds we take clearances, ring gap and parts selection into mind to ensure you have a solid foundation.
