For dedicated naturally-aspirated car fans, the Arrington 440 HEMI Stroker long 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 our 440 short block, we add our custom-engineered high performance cam package and our proprietary ported head and valve package with performance springs and lifters.
Customer must supply buildable block and head cores.
Not recommended and not warranted for forced induction (boosted) applications.
