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.

Core charges for both the block and heads apply if you are not providing them for upgrade.

3 yr / 36,000 mile warranty

Not recommended and not warranted for forced induction (boosted) applications.
