About this part

Product Details

When you're building a high-performance Chevrolet Big Block engine, the pistons are a critical component that needs to handle serious stress. This Manley Performance piston set is designed for builders who demand strength and reliability for their performance builds. They are forged from a domestic 2618 alloy, which is known for its ability to withstand high temperatures and pressures found in powerful engines.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them generate substantial power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to strict standards, which is key for getting a good seal from your piston rings. A good ring seal means more power and better efficiency. These pistons also feature tool steel wrist pins for added durability, and some select Manley pistons offer upgrades to even stronger alloys like 9310 or Turbo Tuff/DLC for extreme applications.

This set is for a 4.560-inch bore with a 1.395-inch compression height and a -3.00cc valve relief. Remember that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built, strong set of pistons for your performance Chevrolet Big Block build, Manley has a solid reputation among professional engine builders.
