Eagle Ford 351W 3.750in Crank 6.250in I-Beam Rods -5cc Flat Top 4.030in Pistons Rotating Assembly

When you're building a Ford 351W engine for street use, especially one that'll run on pump gas and stay naturally aspirated, this Eagle Street & Strip Rotating Assembly is a solid choice. What you get in this package is a complete rotating assembly ready to be installed. It includes a 3.750-inch cast crankshaft, 6.250-inch I-beam connecting rods fitted with 3/8-inch ARP 8740 bolts, and forged 4032 SRP flat-top pistons with a -5cc dish, sized for a 4.030-inch bore. It also comes with plasma-moly file-fit piston rings and King rod and main bearings to get your bottom end buttoned up.

This assembly is put together with components suited for everyday driving and occasional spirited use. The cast crank is a common choice for street applications where extreme stress isn't the primary concern, offering a good balance of strength and cost. The I-beam rods are well-known for their reliability in street performance builds, and the ARP bolts ensure they stay securely fastened. SRP pistons are forged from 4032 aluminum, which offers good thermal expansion properties for street drivability, and the flat-top design with a -5cc dish is ideal for achieving a desired compression ratio with typical cylinder heads on a 4.030-inch bore. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, and King bearings are a popular choice for their consistent performance in a wide range of applications.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's designed for naturally aspirated engines running on pump gas, making it a straightforward option for many street-oriented 351W builds. Ensure you follow proper assembly procedures and torque specifications when installing this rotating assembly into your engine block.
