Manley Ford 4.6L Modular V8 Piston Set - 3.700in Bore 1.220in CH, -23.00 CC

If you're building a high-performance Ford 4.6L Modular V8 engine, these Manley 594470C-8 pistons are a solid choice. They're designed for a 3.700-inch bore and feature a -23.00cc dish, which is important for setting your compression ratio. Manley is a well-known name among engine builders for a reason – their parts are built to handle serious work.

What sets these pistons apart is the material: they're forged from domestic 2618 alloy. This material is chosen for its strength and ability to withstand the high pressures and temperatures found in performance engines. The pistons also feature proven cam and barrel skirt profiles. This design helps them generate power efficiently while also being gentler on your cylinder walls during operation, which can lead to a longer engine life. Manley also pays close attention to the details, like the ring lands and grooves. They machine these to exacting standards to ensure a good seal with your piston rings, which is crucial for making maximum power and preventing blow-by.

Included with these pistons are premium chrome moly wrist pins. These are strong enough for many performance applications, and Manley offers upgrades to even tougher alloys if your build demands it. The unique fixturing Manley uses allows them to machine the skirt and cut the ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, contributing to that all-important ring seal. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
