Eagle Ford 351C 3.850in Crank 6.000in I-Beam Rods -20cc 4.030in Pistons Rotating Assembly

This Eagle Pro Street Rotating Assembly is a solid package for your Ford 351C engine build. What you get is a 3.850-inch forged 4340 crankshaft, paired with 6.000-inch 4340 I-beam connecting rods. These rods come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability in performance applications. The assembly also includes forged 4032 ICON pistons, featuring a -20cc inverted dome design and a 4.030-inch bore size, along with plasma-moly file-fit piston rings. To top it off, it comes with KING XP rod and main bearings, ensuring smooth operation and durability for your engine's core components.

This rotating assembly is specifically put together for naturally-aspirated racing use, meaning it's built to handle the demands of engines that don't rely on forced induction like turbochargers or superchargers. The use of forged 4340 steel for both the crankshaft and connecting rods means these parts are significantly stronger and more durable than cast components, which is crucial for high-performance engines. The ICON pistons are also forged, offering excellent strength-to-weight ratio and resistance to detonation. The file-fit piston rings give you the flexibility to achieve a precise fit in your cylinder bores, which is important for optimal compression and oil control. ARP bolts are a popular choice in performance builds for their consistent clamping force and resistance to stretching under load.

When putting this assembly into your 351C, remember that the piston rings are file-fit, so you'll need to check and potentially adjust their end gap to match your specific cylinder bore dimensions and intended use. This is a common practice in performance engine building to ensure proper sealing and longevity. Also, be aware that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's a well-rounded package for someone looking to build a strong, naturally-aspirated Ford 351C engine.
