Mahle MS piston set for a 348ci-style GM build provides eight forged pistons with a 3.908in bore, 3.622in stroke and 6.125in connecting rods. Each piston uses a 0.927in pin and a modest dish volume (-4.1cc) to achieve roughly a 10.2:1 compression ratio. The matched set supports consistent assembly and reliable replication across all eight cylinders.
