High Horse Performance is Veteran Owned & Operated

This 1000+ horsepower ready 426 Hellcat based stroker engine is the perfect combination for your street rod or high performance street car. Easily swapped into your Hellcat, Trackhawk or TRX and available in both long block and complete versions, just top it off with a factory Hellcat 2.4L or Demon/Redeye 2.7L IHI supercharger or upgrade to the new Whipple 3.0 or Magnusson TVS2650 system for an easy 1000 horsepower pump gas combination or unleash upwards of 1200+ reliable horsepower on higher octane fuels. This rotating assembly utilizes the Callies 8 Counterweight crankshaft and billet rods that are far stronger than your base forged aftermarket parts without the additional costs of expensive billet crankshafts and race-grade connecting rods. This engine is designed to handle at least 1200 horsepower with ease as these same internals are also used in other popular and well known 7.0L HEMI Crate Engines.
