Eagle Chevy 350 3.750in Crank 5.700in H-Beam -18cc 4.040in Pistons Rotating Assembly

This is the Eagle Chevy 350 3.750in Crank 5.700in H-Beam -18cc 4.040in Pistons Rotating Assembly, part number 12304040. It's a complete package designed for serious performance applications, especially if you're planning on using nitrous or forced induction with your Chevy 350 engine. This assembly gives you all the core rotating components you need to rebuild or upgrade your engine's bottom end.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with it are 5.700-inch H-beam connecting rods, which are a popular choice for their robust design. These rods come with 7/16-inch ARP 8740 bolts, a well-regarded name for reliable fasteners in performance engines. The pistons are forged 4032 aluminum from ICON, featuring an -18cc inverted dome design and a 4.040-inch bore size, which helps achieve a specific compression ratio when combined with the rest of the components. You also get plasma-moly file-fit piston rings, allowing for precise ring gap adjustment during installation, and King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This is a competition-level assembly, meaning it's built to handle the demands of racing. Keep in mind that this specific assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure optimal performance and longevity.
