For dedicated naturally-aspirated car fans, the Arrington 440 HEMI Stroker short block gives you our BIGGEST standard upgrade to a 6.1L factory block. Based on the Chrysler 6.1L HEMI block, all of the moving parts are upgraded and forged to create a high-performance platform that is our largest displacement for this block that comes with a warranty.
Starting with this 440 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 increased throttle body size, cold air intake and/or long tube headers -- there is a combination that delivers the power you crave.
Not recommended and not warranted for forced induction (boosted) applications.
A core charge of $2000 is added in the cart.
