Mahle MS Piston Set SBC 358ci 4.030in Bore 3.480/3.5stk 6.125in Rod .927 Pin -5cc 10.4 CR Set of 8

This Mahle MS Piston Set gives you everything you need to rebuild the heart of your Chevrolet Small Block engine. Inside this box, you'll find a complete set of eight forged pistons, each designed to precise specifications for a 358 cubic inch displacement. These pistons feature a 4.030-inch bore and are built to work with a 3.480 or 3.500-inch stroke crankshaft, paired with 6.125-inch connecting rods. The included wrist pins measure 0.927 inches, and each piston has a -5cc dish volume, contributing to a 10.4:1 compression ratio with the specified components.

Mahle chose 4032 aluminum for these pistons, a well-known material for its strength and durability in performance applications. This alloy offers good thermal expansion properties, which is crucial for maintaining proper clearances as the engine heats up. Each piston weighs in at approximately 420 grams, a consistent weight that helps ensure balanced rotating assembly performance. The 4.030-inch bore size is a common specification for many popular Small Block Chevy builds, making this set a solid option for those looking to achieve a 355 cubic inch displacement with a focus on reliable performance.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's recommendations and the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of this high-performance piston set.
