What is the compression ratio impact of the -2cc dish?

The -2cc dish volume is a key factor in determining your engine's final compression ratio. This specification, along with your cylinder head volume and head gasket thickness, will dictate the overall compression. Consult your engine builder or tuning software for precise calculations.

Are these pistons coated?

These Platinum Series pistons feature a moly skirt coating on select part numbers for added durability. The specific coating for this part number should be confirmed with Manley's detailed specifications.

What is the advantage of 2618 alloy forgings?

2618 alloy is a popular choice for performance pistons because it offers excellent strength and toughness. It has better ductility than some other alloys, which helps it withstand the high pressures and temperatures found in performance engines without cracking.

About this part

Product Details

If you're building or rebuilding a Chevy LT1 engine with direct injection, these Platinum Series pistons from Manley are a solid choice. They're designed for a 4.080-inch bore and feature a -2cc dish, which is important for setting your compression ratio correctly. Manley is a well-known name in performance engine components, and their Platinum Series is built to handle serious work.

What sets these pistons apart is the material and the machining. They're forged from domestic 2618 alloy, which is known for being strong and reliable under high stress. You also get premium chrome moly wrist pins included, and Manley pays close attention to the ring lands and grooves. This means a better seal for your piston rings, which translates directly into more power and better efficiency. The cam and barrel skirt profiles are also carefully designed to help the piston move smoothly in the cylinder, reducing wear on your cylinder walls while still making good power.

Manley uses a unique fixturing process that allows them to machine the skirt and the ring grooves in the same operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is critical for proper ring seal and preventing blow-by. These pistons are a popular choice among professional engine builders for a reason – they're well-made and perform consistently.
