Mahle MS Piston Set SBC 358ci 4.030in Bore 3.480/3.500stk 6.0in Rod 0.927 Pin -5cc 10.4 CR Set of 8

This Mahle MS Piston Set is designed for Small Block Chevy engines, specifically for builds around 358 cubic inches with a 4.030-inch bore. What you get in this set are eight forged pistons, ready to be installed in your engine. These pistons feature a flat-top design with a -5cc dish, which helps achieve a 10.4:1 compression ratio when paired with a 3.480 or 3.500-inch stroke crankshaft and a 6.000-inch connecting rod. The included 0.927-inch wrist pins are also part of this comprehensive package.

Mahle is known for making well-built engine components, and these pistons are no exception. They are constructed from 4032 aluminum, a material chosen for its strength and ability to handle the stresses of performance engines while maintaining good thermal expansion properties. This makes them a solid option for builders looking for reliable performance. The flat-top design with the specific valve pocket depth is engineered to work with a particular combination of stroke and rod length, aiming for that 10.4 CR target. This precision in design means you're getting pistons that are meant to integrate smoothly into your engine build.

When you're putting together a performance engine, the details matter. This set is intended for a specific engine configuration, so it's important to ensure your crankshaft stroke (3.480 or 3.500 inches) and connecting rod length (6.000 inches) match up to achieve the desired compression. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
