What is the purpose of the cam and barrel skirt profiles on these pistons?

The cam and barrel skirt profiles are designed to optimize the piston's movement within the cylinder. This design helps to reduce friction and minimize wear on the cylinder walls, contributing to both performance and engine longevity.

What type of wrist pins are included with this piston set?

This piston set comes standard with tool steel wrist pins. These are known for their strength and ability to withstand the high stresses encountered in performance engines.

What does the -4.00 CC dish volume mean for my engine build?

The -4.00 CC dish volume refers to the shape and depth of the piston's top. This specification is important for calculating the engine's final compression ratio when used with specific cylinder heads and crankshafts, allowing tuners to achieve desired performance characteristics.

About this part

Product Details

Built from domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds. The 4.040-inch bore size is a common starting point for many Chevrolet Small Block engine rebuilds, and the -4.00 CC dish helps achieve a desired compression ratio when paired with appropriate cylinder heads and crankshafts. Manley's signature cam and barrel skirt profiles are engineered to reduce friction and wear on cylinder walls while still generating substantial power.

You'll find exacting standards applied to the ring lands and grooves, which is crucial for achieving a solid seal and maximizing the power your engine can produce. Each set comes standard with tool steel wrist pins, known for their strength and durability under high stress. For those pushing the limits, Manley offers upgrades to even stronger alloys. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other for optimal performance and longevity.

When you're building a high-performance engine, the details matter. These pistons are a popular choice among professional engine builders and tuners who demand reliability and performance. 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.
