Chevy 400 Speed Pro Pistons
This is a set (8) of Speed Pro hypereutectic Chevy 400 pistons - H616CP. +40 bore. Flat top piston with 4 valve reliefs. Anti-friction coated skirts. For use with 5.7" connecting rods. Includes pins and wire locks. Can be used with either pressed fit or bushed rods.
These hypereutectic Speed Pros are perfect for stock to moderate performance rebuilds. Silicone aluminum alloy allows them to run with tighter clearances, less friction, and increased sealing. Higher strength compared to regular cast pistons. Duroshield coating on piston skirts delivers longer life and reduced friction.
