Mahle MS Piston Set SBF 410ci 4.040in Bore 4.000in Stroke 6.25in Rod .927 Pin -26cc 9.5 CR Set of 8

If you're building a high-performance Ford Small Block engine to displace 410 cubic inches, a solid set of pistons is where you start. This Mahle MS Piston Set is designed for that kind of build, featuring a 4.040-inch bore and a -26cc dish that helps achieve a 9.5:1 compression ratio with a 4.000-inch stroke crankshaft and a 6.250-inch connecting rod. These pistons are forged from 4032 aluminum, a material known for its strength and ability to handle the stresses of performance applications while maintaining good thermal expansion properties, which is crucial for longevity in a performance engine.

Mahle has a long-standing reputation in engine building, and this MS series piston set reflects that. The pistons are designed with a 4.040-inch bore and a 1.245-inch compression height, paired with a .927-inch pin diameter. At 426 grams each, they offer a good balance of strength and weight for a performance build. This set includes all eight pistons needed for a V8 engine, ensuring you have matched components for consistent performance across all cylinders. Remember that these pistons are not CARB approved and cannot be shipped to California.

When undertaking a performance engine build of this caliber, it's important to ensure all components work together. This piston set is a key piece for a 410ci Ford Small Block, but you'll also need to consider crankshafts, connecting rods, camshafts, cylinder heads, and proper tuning to get the most out of your engine. Always refer to the manufacturer's installation instructions for specific details regarding clearances, ring installation, and assembly.
