Description Technical Specs Engine Info
 



This 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.

These engines can be used for a Gen III application, but you will need to purchase a conversion package.
