Product Details
If you're building a high-performance Chevrolet Small Block engine, getting the right pistons is a critical step. These Manley Platinum Series pistons are designed for serious engine builders who demand strength and reliability. They feature a 4.040-inch bore and a -4.0cc dome, making them suitable for a wide range of performance applications where precise compression ratios are key.
Manley uses domestic 2618 alloy forgings for these pistons, which are known for their exceptional strength and ability to withstand the high pressures and temperatures found in performance engines. The pistons also come with premium chrome moly wrist pins, and Manley's cam and barrel skirt profiles are carefully engineered to generate power while minimizing wear on your cylinder walls. They also pay close attention to the ring lands and grooves, ensuring a tight seal for maximum power output. The unique machining process ensures the ring grooves are perfectly square to the piston skirt, which is vital for proper ring function.
These pistons are a solid choice for anyone looking to build a robust and powerful Small Block Chevy. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
