About this part

Product Details

Manley Performance is well-known for making strong engine components, and this rotating assembly is a prime example of their work for the Ford 351 Cleveland. If you're building a high-performance engine and need a solid foundation, this kit is designed to handle serious power. It includes everything you need to get your short block assembled with top-tier parts.

At the heart of this assembly is a 4340 forged steel crankshaft, chosen for its exceptional strength and durability under high stress. Paired with this are their Pro Series I-Beam connecting rods. These are lightweight yet incredibly strong, featuring 7/16? ARP 2000 cap screws for secure rod cap retention, which is crucial when you're pushing an engine hard. The kit also comes with 2618 forged aluminum Platinum Series pistons. Forged aluminum is ideal for high-performance applications because it offers a great strength-to-weight ratio and can withstand the heat and pressure of combustion. These pistons include Premium Chrome Moly wrist pins for added reliability. Topping it off, you get high-performance piston rings and high-performance Clevite H Series rod bearings (narrowed) and P or H Series main bearings, all selected to work together for optimal performance and longevity.

This is a comprehensive kit for rebuilding or upgrading your Ford 351 Cleveland engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
