If you’re building a high-output small-block Mopar, the Scat rotating assembly you see here takes the guesswork out of piecing together internal components. This competition-grade Scat Chrysler 360 4340 Forged Standard Weight Stroker Rotating Assembly ships as a precision-matched kit that includes forged crank, connecting rods, pistons, rings, and bearings—everything needed to create a robust, high-displacement engine short of cam, heads, or induction.

What truly sets this unit apart is its use of a forged 4340 steel crank—machined to standard weight tolerance and nitride hardened for excellent wear resistance—providing the strength needed for aggressive stroke and power builds. The I-beam connecting rods use 7/16" cap bolts and are forged from premium steel, giving you confidence under harsh conditions. Pistons and rings are assembled with proper clearances and matched to the rotating components to reduce break-in variables.

This kit supports multiple bore and stroke options—typically built around the 360 main journal spacing with stroke options like 3.580" or 4.000"—so you can configure displacement for 365 or 408 cubic-inch builds. Because it’s supplied as a complete rotating package, you avoid the pitfalls of mixing unmatched components and reduce assembly stress.

Whether you're building a tough street/strip motor or a race-only animal, this mopar 360 stroker kit option gives you a balanced, high-quality foundation. Its design handles high RPM loads, helps maintain internal durability, and ensures consistent performance. Step up to a fully integrated kit, install it properly, and let your build benefit from a cohesive, race-minded foundation.
