The Arrington 392 Stroker is useful for applications that require a forged block and rotating assembly and the Chrysler 6.1L engine block is an excellent base from which to start. 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.

A core charge of $2000 will be automatically added in the cart.
