About this part

Product Details

If you're building a high-performance Chevy 350 engine for serious racing, especially with nitrous or forced induction, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of competition. It includes all the key components you need to build a robust short block, ready to be assembled into your project.

At the core of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability under high stress. Paired with it are 5.700-inch 4340 H-beam connecting rods, known for their solid construction and ability to withstand significant loads. These rods come equipped with 7/16-inch ARP 8740 bolts, a name trusted for their reliability in high-performance applications. The pistons are forged 4032 Mahle units, featuring an inverted dome design with a -26cc volume and a 4.040-inch bore size, which helps achieve a desired compression ratio for boosted or nitrous applications. They also include plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To top it off, the assembly comes with King XP rod and main bearings, offering excellent wear resistance and smooth operation.

This rotating assembly is a well-built package for those pushing the limits of their Chevy 350. Please note that this assembly is not CARB approved and cannot be shipped to California. It's essential to consult with your engine builder or refer to manufacturer instructions for proper assembly and installation procedures, especially when dealing with file-fit rings and bearing clearances.
