What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for demanding engine builds.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to optimize piston movement within the cylinder. This design helps generate substantial power while also being gentle on the cylinder walls, reducing wear over time.

Are these pistons compatible with all Ford Small Block engines?

These pistons are designed for Ford Small Block engines with a 4.040-inch bore and a -3.50 CC dish. It is essential to verify that these specifications match your specific engine build requirements and that they are compatible with your chosen cylinder heads and crankshaft.

About this part

Product Details

Manley Performance is well-known for building robust engine components that professional builders trust. This piston set for Ford Small Block engines is a prime example, designed to handle the demands of a performance build. These pistons feature a 4.040-inch bore and a -3.50 cubic centimeter dish, making them suitable for specific compression ratio targets in your engine build.

Crafted from domestic 2618 alloy forgings, these pistons offer superior strength and durability, which is crucial for engines that see hard use. They incorporate proven cam and barrel skirt profiles, designed to generate power efficiently while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, promoting a better ring seal for improved power output. Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring ultimate squareness between the ring grooves and the piston skirt. Each set includes premium chrome moly wrist pins, with options available for upgraded alloys for even greater durability in high-stress applications.

When building a performance Ford Small Block, choosing the right internal components is key. These Manley pistons are a solid option for those looking for well-built internals that can stand up to the rigors of performance driving. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
