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 our 392 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

Note: the 426 is far more popular and just as reliable, with more displacement. Please compare.
