Mahle MS Piston Set SBC 361ci 4.05in Bore 3.500in Stroke 5.7in Rod .927in Pin -4cc 10.7 CR Set of 8

If you're building a high-performance Chevrolet Small Block engine, getting the right pistons is crucial for power and reliability. This Mahle MS Piston Set is designed for 361 cubic inch displacements, featuring a 4.050-inch bore and a 3.500-inch stroke, which is a common combination for many performance builds. The pistons have a -4.1cc dish volume, working with a 5.700-inch rod length to achieve a 10.7 compression ratio, ideal for naturally aspirated or forced induction applications where pump gas is used.

Mahle uses 4032 aluminum alloy for these pistons, which is known for its strength and durability while still offering good thermal expansion properties. This material choice helps ensure the pistons can withstand the rigors of performance driving. Each piston weighs in at 437 grams, contributing to a balanced rotating assembly. The included wrist pin is 0.927 inches, a standard size for many performance connecting rods. This set includes all eight pistons needed for a V8 engine.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning to ensure optimal performance and longevity of your new engine build.
