Manley Rotating Assembly, SBC 355 3.480 STROKE/-4cc FLAT

What you get in this Manley rotating assembly is a complete package to rebuild the heart of your Small Block Chevy engine. Inside this box, you'll find a lightweight 4340 forged steel crankshaft, a set of Manley's Pro Series Lightweight I-Beam connecting rods fitted with 7/16? ARP 2000 cap screws, and 2618 forged aluminum Platinum Series pistons complete with Premium Chrome Moly wrist pins. This assembly is built for serious performance, capable of handling up to 750 horsepower with the included ARP 8740 bolts, and can be upgraded to handle an impressive 1,500 horsepower with optional ARP 2000 cap screws.

The crankshaft is forged from 4340 steel, a strong material chosen for its ability to withstand high stress and rotational forces common in performance engines. Paired with these are the Pro Series I-Beam connecting rods, also designed for strength and reduced weight to help the engine rev more freely. The Platinum Series pistons are forged from 2618 aluminum, a popular choice for high-performance applications due to its thermal expansion properties and durability under extreme heat and pressure. The flat-top piston design with a -4cc dish is specifically chosen for certain compression ratio targets in a 355 cubic inch SBC build.

This assembly is a solid option for builders looking to significantly increase the power output of their Small Block Chevy. It's important to note that this specific assembly is not CARB approved and cannot be shipped to California. Always refer to Manley's detailed specifications and recommended build procedures to ensure optimal performance and longevity for your engine project.
