Better Built Forged Short Blocks have a proven record. This 6.1L forged short block is the answer for getting more power from a blower or nitrous. These are rated at 800HP as a standard build and can hold 1500HP + when custom building your short block. 100% machined and assembled in house to ensure quality you won't find with some of the other HEMI builders. Let us build the engine that suits your needs.
