Manley Ford 4.6L Modular V8 Piston Set - 3.552in Bore 1.220in CH, -23.00 CC

If you're rebuilding the engine in your Ford 4.6L Modular V8, especially for a performance application, a solid set of pistons is crucial. These Manley Performance pistons are forged from 2618 alloy, a material known for its strength and ability to handle the stresses of high-performance engines. They feature a -23.00cc dish, which is important for achieving the correct compression ratio with your specific cylinder heads and camshafts.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them run true in the cylinder bore, reducing noise and wear while still allowing for maximum power output. The ring lands and grooves are machined to very precise standards, which is key for getting a good seal from your piston rings. A good ring seal means better compression, more power, and less oil getting into the combustion chamber. These pistons also come with 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 builds.

When building a serious engine, attention to detail matters. Manley's unique fixturing process allows them to machine the piston skirt and the ring grooves in one setup. This ensures the ring grooves are perfectly square to the piston skirt, which is essential for optimal ring seal and overall engine performance. These are well-built components designed for builders who demand reliability and power from their engines.
