One of the most popular Arrington upgrades for the 5.7L HEMI engine is the 392 cubic inch stroker, the Arrington 392 short block. All of the moving parts are upgraded and forged to create a high-performance platform for forced induction, aggressive camshaft profiles, and other power add-ons.  

Starting with this 392 short block, this customizable HEMI can be modified to come alive. By adding our custom engineered high performance cam package and our proprietary ported head package, a supercharger, increased throttle body size, cold air intake and/or long tube headers -- there is a combination that delivers the power you crave.
