Manley Chevrolet Small Block Piston Set - 4.060in Bore 1.550in CH, -4.00 CC

If you're building a high-performance Chevrolet Small Block engine, this Manley Piston Set is a solid choice. These pistons are designed for a 4.060-inch bore and feature a -4.00 CC dish, which is important for setting your compression ratio. Manley is a well-known name in performance engine building, and these pistons are part of their "Platinum Series," meaning they're built for 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 performing well under high stress. You also get tool steel wrist pins included, which are tough enough for demanding builds. Manley pays close attention to the details, like the exacting standards for ring lands and grooves to ensure a good seal, and the cam and barrel skirt profiles. These profiles are designed to help the piston move smoothly in the cylinder, generating power while also being easier on your cylinder walls. They even use unique fixturing to make sure the ring grooves are perfectly square to the skirt, which is crucial for proper ring seal and overall engine health.

This set includes eight pistons, eight wrist pins, and eight sets of wrist pin locks. Remember, these pistons are not CARB approved and cannot be shipped to California. If you're aiming for a powerful and durable Small Block Chevy, these Manley pistons are a great foundation.
